Investigation of the excitation function in the Y2O3 : Eu-Gd2O3 : Eu system in the voltage range 300-1000 V

摘要

This paper discusses how the cathodoluminescence intensity of europium-doped solid solutions of (YGd)(2)O-3 in the range of accelerating voltages 300-1000 V depends on the energy and calculated values of the penetration depth of primary electrons into a layer of luminescent material. The thickness of the "dead" layer is determined to be 9-11 nm, and it is shown that it depends oil the conditions under which the solid solutions are synthesized. It follows from these results that it is necessary to use different compositions of the phosphor matrix, depending oil the accelerating voltage applied to the display.
