Description

Abstract: Many properties of corundum, including the radiation and thermal resistance, large forbidden zone, high light output, and spectral and temporal characteristics, make it an attractive converter for UV and particle detectors.
We have at our disposal many corundum crystals of different thicknesses with various activators, which were studied in the UV range of the spectrum. The percentages of various mixtures in the newly synthesized crystals were determined in order to determine the composition of impurities that ensures the maximum conversion of UV radiation.
Studies of these crystals led to the conclusion that corundum can be used in as a photoconverter not only in the UV range but also for creating sensitive detectors in the VUV wavelength range.
