Temperature and Time Stability of Luminiferous Coating on Basis of Yttrium Aluminium Garnet alloyed By Cerium
Abstract
The effect of temperature and operation time on the value of quantum efficiency of aluminiferous coating is determined. It is shown that the basic contribution to the decrease of its value is made by thermal quenching of luminescence and degradation processes in the aluminiferous coating, caused by the physicochemical interaction of luminophore with silicon-organic ligament.
