Optical properties of diffuse ZnSe:Mn layers

It is shown that doping of zinc selenide with Mn atoms from the vapour phase causes appearance of the band peaked at hw= 2.3 eV in the luminescence and transmission spectra. The intensity of this band changes with the temperature of diffusion annealing and varies after introduction of other doping impurities to the basic substrate, which could be explained by increased solubility of Mn atoms.
