Radio- and VUV - Excited Luminescence of YAP:Ce, YAP:Pr and YAG:Pr
Abstract
In this Communication we report initial results of studies on X-ray and VUV excited luminescence of YAP and YAG crystals activated with Pr(3+), and YAP activated with Ce(3+). Excitation and luminescence spectra of Pr(3+) and Ce(3+) d-f and Pr(3+) f-f emissions and luminescence time profiles under pulsed synchrotron excitation are presented and analysed in order to identify and characterize various host-to-ion energy transfer channels. The results support the notion that direct and trap mediated capture and recombination of holes and electrons via Pr(3+) or Ce(3+) ions provide the dominant mechanism of radioluminescence production in both YAP and YAG crystals.
