摘要：

Spectra of stationary and stimulated luminescence of SrS: Eu, Sm and CaS: Eu, Sm were studied. The differences in spectral characteristics of the studied compounds were established. It was determined that in an excitation spectrum of the calcium sulfide phosphors, unlike strontium sulfide the band with wavelength of lambda = 350 nm is presented. Due to this band the increase in a level of steady luminescence takes place at UV excitation of this phosphor in a range of lambda max = 365 nm.
