摘要：

Polycrystalline zinc selenide is doped with an iron impurity to a concentration of similar to 10(19) cm(-3) in a zinc vapor atmosphere by the thermal diffusion method, and the distribution profile of optically active iron Fe2+ is obtained. The effect of the Fe2+ concentration on impurity-and defect-related ZnSe luminescence spectra at low temperatures is determined. In the range of 1.28-1.31 eV, a luminescence line with a decay time of similar to 0.341 ms is detected, with its intensity increasing in regions with Fe2+ concentration close to the maximum one. The line is attributed to the luminescence center arising due to the Fe2+ interaction with a background impurity or defect in ZnSe.
