Abstract

Nominally pure CaF₂ crystals were grown by Stockbarger method. Pulse cathodoluminescence (PCL) spectra were studied. PCL spectra of CaF₂ crystals at room temperature were excited by pulse of accelerated electrons and simultaneous stimulated emission of CdSSe crystal. It was shown that the simultaneous excitation of the crystals CaF₂ leads to a reduction efficiency of creation of self-trapped excitons (STEs) and the appearance of short-lived emission in the UV region of the spectrum.
