organicka elektronika a fotonika

The laboratory deals with applied and basic research of advanced organic materials in electronics and photonics. We are offering expert advice in the field of organic synthesis of functional materials, characterization and study of their electron, optical, electric and optoelectric properties and design, construction and characterization of components and devices for organic electronics, sensorics and photonics.

RESEARCH FOCUS

The laboratory is specialized in the synthesis of new functional materials, thin film deposition and characterization, design of prototypes and model components and studies of the performance of all these parts. Emphasis is particularly placed on identifying and understanding the relationship between the structure of molecules and their monitored properties, which affect not only their molecular parameters, but also the nano-, micro-and macroscopic properties. Among the materials studied are oligomers and polymers, low molecular weight substances and biological and bio-analogous components. These then form the active parts of devices such as organic solar cells, organic luminescent diodes and displays, sensors and optical devices. The laboratory cooperates with many domestic and foreign organizations and industry partners. Initiates, solves, and participates in resolving national and international projects also in the European Union Framework Program.

In terms of instrumentation the Laboratory of organic electronics and photonics consists of five areas: (i) Organic synthesis, which deals with the design, synthesis and chemical modification of new functional molecules, (ii) Optical characterization that examines electron phenomena in the studied materials and devices through basic and advanced optical methods, (iii) electronic and opto-electronic characterization focused on electric phenomena (generation, transport and recombination of charge), (iv) dielectric spectroscopy focused on the study of dielectric spectra using Impedance spectroscopy and ellipsometry and (v) Thin films deposition where a wide range of techniques is available for application of the solution and solid phase deposition.

 

  • ORGANIC SYNTHESIS

    Laboratory of organic synthesis is part of Material research center with extensive experience in organic chemistry and technology. The laboratory is focus on research and development of new organic compounds, oligomers and polymers especially used in organic electronics as well as custom synthesis of chemical specialties for pharmaceutical and chemical industry.

    Fundamental research platform is focused on the synthesis of heteroaromatic compounds, knowledge of organometallic chemistry and other more conventional fields of organic synthesis which leads to the preparation of new molecules with potential industrial application.

    Laboratory of organic synthesis provides wide range of services - laboratory research and development, scale up with connection to pilot plant production and cooperation with Czech and foreign companies.

  • OPTICAL CHARACTERIZATION

    The laboratory is focused on the characterization of electron processes using optical methods. The basic characterization include absorption and fluorescence spectra, as well as the determination of quantum yields and fluorescence lifetimes of excited states. The laboratory also studies the charge and energy transfer in systems for organic electronics (solar cells, electroluminescence diodes) and biological materials (DNA). Attention is also focused on research of materials for use in nonlinear optics (e.g. two-photon absorption) and for the construction of organic solid-state lasers (e.g. amplified spontaneous emission).

    In addition to standard equipment for the characterization of absorption and fluorescence spectra, anisotropy, quantum yields and lifetimes of excited states, we have also a modular equipment, which can be configured according to the requirements of a particular experiment. This allows us to carry out special experiments which are not possible or too costly with commercial facilities. There is also the possibility to measure samples in the vacuum, in an inert atmosphere and at low temperatures (77K).

    • Absorption and fluorescence spectrophotometers
    • Pulsed picosecond Nd:YAG laser with 2nd, 3rd and 4th harmonics
    • Tunable pulsed picosecond optical parametric generator (available soon)
    • Intensified CCD camera for spectroscopy (gated from 2ns) with spectrograph
    • Photomultiplier tubes for UV, VIS and NIR
    • Monochromators, continual and pulsed light sources, energy meters and other equipment

  • ELECTRONIC AND OPTOELECTRONIC CHARACTERIZATION

    Electronic and optoelectronic characterization techniques are useful for both fundamental and application level investigations of (mainly) disordered materials – polycrystalline, amorphous and organic metals, semiconductors and insulators. The fundamental level consists of a determination of the electronic structure (energies of conduction and valence bands, energy gap and doping levels) and charge fotogeneration, transport and recombination in the materials under study. The application level of the method consists of semiconductor device characterization, e. g. rectifying and electroluminescent diodes, solar cells, field effect transistors and sensors.

    The majority of the equipments fulfill the specific requirements for low voltage (nano- and microvolts) and low current (from the level of hundred femtoampers) electrical measurements. The experimental setups are predominantly computer controlled, which facilitates and precise the measurement. The characterization can be performed under vacuum to prevent device degradation.

    The staff is not only experienced in performing the measurement but also development of both hardware and software of the devices. In this way specific customer requirements could be fulfilled.

    • Photoconductivity (spectraly and time resolved) characterization
    • Solar simulator (class AAA) with complete solar cells characterization (LotOriel)
    • Electroluminescence – integral and spectrally resolved
    • Current - voltage characterization aparatus
    • Temperature-modulated space-charge limited current spectroscopy (TM-SCLC) (under construction)
    • 4 – point resistivity measuring equipment
    • Organic field effect transistor (OFET) characterization
  • DIELECTRIC SPECTROSCOPY

    • Impedance analyzator
    • Elipsometer Uvisel (Horiba JobinYvon)

  • THIN FILMS DEPOSITION

    The equipment available covers the basic and advanced techniques for thin film deposition. The accent is put on the „wet“ and low-cost techniques, but the vacuum deposition (including plasma enhanced processes) plays also an important role.

    The spin-coating and ink-jet printing techniques are proper for thin film deposition from solubilized materials, whereas the vacuum techniques could handle cases of insoluble low molecular weight compounds. The spray and electrophoretic techniques are developed nowadays in a way to be used for weakly soluble substances. The deposition techniques will be transferred into a cleanroom. Moreover a deposition under protected condition (glovebox) will be also available.

    • Ink-jet printer Dimatix
    • Spin-coating facilities
    • Spray deposition setup (under development)
    • Electrophoretic deposition setup (under development)
    • Vacuum evaporation system
