    Opis:
    Two heteroleptic charged iridium (III) species comprising two cyclometallating ligands and a neutral diimine ligand were synthesized and characterized, namely [(3,4,7,8-tetramethyl-1,10-phenanthroline-N-N')-bis-(2-(2,4-difluorophenyl)-5-(trifluoromethyl)pyridine-$C^{6'}$,N)-iridium (III)]hexafluorophosphate (UM01) and [(3,4,7,8-tetramethyl-1,10-phenanthroline-N-N')-bis-(2-(2',4'-difluoro-phenyl)-1H-pyrazole-C^{6'},N)-iridium (III)]hexafluorophosphate (UM02). Both complexes were used as the blue emitter in OLED and LEC devices. We found that the optimized structure is ITO/PEDOT:PSS/complex:BMIMPF₆(1:1)/Al. The UM01 gave a current efficiency of 1.14 cd $A^{-1}$, whereas the UM02 shows a better CIE coordination at 0.19, 0.40.

    Opis:
    Microbolometers are the most widely used detectors in long-wave infrared uncooled thermal imagers. An optical cavity is required within a microbolometer structure to increase its optical absorption. In this work we present a detailed study on the design and optimization of a microbolometer optical cavity using Essential-Macleod package. In the simulations, the cavity is considered as thin film multi-layers that form cascaded Fabry-Perot optical cavities. In the design phase, the structures of layers are selected, which includes selection of materials and initial thickness. The absorbing layers are chosen to be made of vanadium-pentoxide (V₂O₅) and titanium (Ti). In the optimization phase, the designed layer thicknesses are varied to maximize optical absorption within the absorbing layers. The simulations show that Ti layer absorption dominates over the V₂O₅ layer. Also, the optimization proves that the thickness of cavity's air-gap is not equal simply to quarter-wavelength, because of the presence of a complex cascaded Fabry-Perot structure. The optimized air-gap thickness is found to be ≈ 3.5 μm at wavelength of 10.6 μm.

    Opis:
    The paper presents the construction and test results of a long-term radiation detector module for free space optical communication operated at the wavelength range of 8-12 μm. In the module a Polish detector manufactured in the company Vigo System S.A. was applied. High sensitivity of the detection module was achieved through a multi-layered heterostructure HgCdTe with immersion lens, which is optimized for the radiation detection at the wavelength of 10 μm. Detector noises were reduced as a result of detector cooling by means of four-stage thermoelectric cooler. The developed detection module is dedicated to design a next-generation optical data link. The link will be characterized by a greater range in difficult weather conditions in relation to the currently offered links operating at the shorter wavelengths.

    Opis:
    The paper presents a prototype of a driving system designed to laboratory investigations of quantum cascade lasers. Significant requirements of these lasers operation, as well as a construction of the main components of the system were analyzed. During the performed investigations, a tuning range of both current pulses and temperature control operation were determined. Additionally the method of monitoring both current and voltage of the lasers was also described. As a summary, results of laboratory studies of the system with the use of commercial quantum cascade lasers were presented.

    Opis:
    We have studied a series of polar InGaN/GaN light emitting diodes, consisting of either a blue (440-450 nm) quantum well, or combination of blue and violet (410 nm) quantum wells (with indium content 18% and 10%, respectively). The blue quantum well was always placed close to p-type region of the particular LED. We found that the electroluminescence induced by low current is characterized by light emission from the blue quantum well only. In comparison, optical excitation of our LEDs leads to light emission with energies characteristic either for blue and/or violet quantum wells. The corresponding microphotoluminescence spectra evolve depending on external polarization and variable light intensity of excitation supplied by He-Cd laser. Interplay between built-in electric field and externally applied polarization/screening decides about the band structure profiles and thus radiative recombination mechanisms.

    Opis:
    In this paper we investigate interband cascade type-II mid-wavelength infrared InAs/GaSb superlattice detector in temperature range from 200 K to 300 K. The paper is based on the theoretical calculation of dark current treated as a sum of two components: average bulk current and average leakage current, flowing through the device. The average leakage current results from a comparison of theoretically calculated bulk current and measured one. We show that it is possible to fit theoretical model to experimental data, assuming that transport in absorber is determined by the dynamics of the intrinsic carriers. Based on the fit we estimated carrier lifetime greater than 100 ns in temperature range 200-300 K.
