Abstract

This investigation is dedicated to studying of peculiarities of luminescent properties of the single crystalline films (SCF) of Al₂O₃-Y₂O₃-R₂O₃ oxide system with alpha-Al₂O₃ and garnet structure, which are used as various types of ionizing radiation luminescent detectors. These peculiarities define the number of nontrivial advantages over their volume analogues. It is shown that SCF are characterized by the low concentrations of vacancy type defects and substituent defects, and the high concentration of Pb ion as dopant. This allows us to substantially increase the spatial resolution and selectivity of cathodoluminophores on the base of these compounds.
