Abstract

Different electroluminescence spectrums of the blueλmax=420 nm wide-banded low-temperature low-voltage radiation of CdF2-RE films at different levels of excitation in the region of temperatures of 77–300K are investigated. The kinetic characteristics and temperature dependence of this radiation are explored. An effect of the resonance interaction of the centers of luminescence of the wide-band and line radiation of the RE-centers is found. A model of the center of the wide-band radiation is suggested. It is shown that the “blue” radiation is caused by recombination of the carriers.
