Abstract :
Photoluminescence spectrum of Ce:YAG single crystal was studied employing vacuum ultraviolet (VUV) synchrotron radiation. Intrinsic absorption edge at about 52,000 cm−1 was observed in the absorption spectrum. From the VUV excitation spectrum, the energy of the highest d-component of 53,191 cm−1 (188 nm) for the Ce3+ ions in YAG was obtained at 300 K. The disappearance of the third 5d level at 37,735 cm−1 (265 nm) in absorption and excitation spectra in our samples may be due to the impurity Fe3+ ions absorption.
