Description
In the spectrum of low temperature photoluminescence of the fine-grained ( ) thin films is discovered a band of the own ( ) radiation, specified by the subsurface potential barriers on border of crystalline grains and marginal double-acting band, appearing as phonons repetitions of the band. The alloyage of the film by impurity leads to stewing double-acting band, but its further thermal processing to activation of the own band, short-wave offset of the red border ( ) and modulation of the full width on half maximum ( ) which is correlated with by the height of the micro potential barriers and temperature of recombined hot photocurrents
