Abstract

In this communication we report initial results of studies on x-ray and VUV excited luminescence of YAP and YAG crystals activated with Pr³⁺ and YAP activated with Ce³⁺. Excitation and luminescence spectra of Pr³⁺ and Ce³⁺ d-f and Pr³⁺ f-f emissions and luminescence time profiles under pulsed synchrotron excitation are presented and analyzed 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 Pr³⁺ or Ce³⁺ ions provide the dominant mechanism of radio luminescence production in both YAP and YAG crystals.
