Abstract

A mixed crystal Sm²⁺-doped Mg_0.5Sr_0.5FCl_0.5Br_0.5 has a high potential in the application for a 3D optical memory. We have observed one-photon persistent spectral hole burning in this material at room temperature. The powder sample of (formula available in paper) was synthesized by firing at 1000 degrees C for 2 hours in a reducing stream of hydrogen. The product was examined with an X-ray diffractometer for the crystalline structure. Fluorescence excitation and emission spectra were recorded with a spectrofluorometer.
