This paper reports optical absorption spectra and rapidly decaying luminescence of BaF2 crystals measured at 295 K under excitation pulse of accelerated electrons and excited simultaneous stimulated emission of CdSe crystal. It is shown that the simultaneous excitation of the crystals BaF2 pulse accelerated and SE semiconductors in electronic components STE absorption leads to a reduction efficiency of creation of STE and the appearance of fast decaying emission in the UV region of the spectrum.

This paper reports the quantitative characteristics of photoluminescence of phosphors powders based on yttrium-aluminium garnets. It contains spectra of excitation, spectra of luminescence with initiating through radiation of xenon lamps and chip with a different power, and kinetic characteristics.
