External photoelectric effect in CaF2:Sm2+ crystals under irradiation with visible light

Academic Article


  • External photoelectric effect is registered in CaF2:Sm2+ crystal under irradiation with visible light, the effect being explained by the photoionization of the impurity ions Sm2+. The spectral dependence of the photoelectric effects is studied and its quantum yield estimated. The results obtained are compared with the previously known data of the photoconduction of fluoride crystals. © 1993.
