Preparation and properties of pyroelectric detectors for optoelectronic applications /III
Novotný, Jan; Zelinka, Jiří; Podvalová, Zdislava; Malina, Václav; Vávra, Vladimír; Franc, J.; Fronc, Václav; Fronc, Václav
2003 - Czech
The single crystals of TGS doped with Pt-ions and with L-alanine were grown as in ferroelectric phase as the full-shaped crystals. The growth rate along the axis c of the doped crystals is much higher than in an undoped one. Morphology, domain structure and hysteresis loops were investgated. The effect of the dopant on the growth velocity is explained on the basis of catalytic action of platinum complexes. The pyroelectric detectors were prepared from these materials and their parameters are presented. Ve výzkumné zprávě je popsána technologie přípravy jednodoménových směsných monokrystalů síranu triglycinia a L-alaninu, legovaných komplexotvornými ionty platiny. Plnoploché monokrystaly byly pěstovány z nízkoteplotního roztoku metodou řízeného snižování teploty. Získané materiály byly testovány z hlediska morfologie, doménové struktury a základních ferroelektrických vlastností. Ze zhotovených monokrystalických výbrusů, orientovaných kolmo k ferroelektrické ose byly ve spolupráci s a.s. TESLA BLATNÁ připraveny čtvercové detektory záření a testovány jejich fyzikální a provozní vlastnosti. Zpráva dále obsahuje rozbor možností aplikace připravených detektorů v systémech pro detekci plynů, které mohou nalézt uplatnění v chemii, ekologii a v bezpečnostních vojenských aplikacích.

Photodynamic therapy. Instrumental optics
Votruba, J.; Stádník, Bohumil; Javorský, Stanislav
2003 - English
Photodynamic therapy of cancerous tumorous of various human organs uses both coherent and noncoherent light sources for the treatment. However, noncoherent ones are prefered due to higher treatment efficiency, simpler and reliable operation and lower financial costs. Main purpose of this report is to give overview of basic optical methods and instruments used in the photodynamic therapy.
