2000 - Czech
The photodetectors operating in the 0.8-20ćm wavelength region have been prepared. The report is devoted to the research and realisation of novel types of materials on the basis TGS single crystals family. The prepared detectors have been tested in static and dynamical regime of operation. The obtained results have been passed on TESLA BLATNÁ Company. Výzkumná zpráva obsahuje výsledky přípravy fotodektorů pracujících v oblasti vlnových délek 0.8-20ćm. Výzkum je věnován přípravě nových typů materiálů pro detektory záření na bázi monokrystalů skupiny látek typu TGS. Připravené infradektory byly testovány ve statickém a dynamickém režimu. Získané výsledky byly předány do a.s. TESLA BLATNÁ na základě smlouvy o spolupráci. Keywords: sensors; infrared detectors; crystal growth Available at various institutes of the ASCR
