Description
The aim of this work is the investigation of the optical properties of (CuInSe2)X - (2ZnSe)1-X solid solutions (CIZS) films with the zinc concentration in the range of 0.0 - 8.0 at. %. Photoluminescence and optical absorption spectra were measured at temperature from 80 to 300 K to characterize defects and structural quality. PL spectra at T = 300 K and 80 K had only one broad recombination band. The observed luminescence peak could be ascribed to donor-acceptor pair (DAP) recombination due to the native defect concentration. It was established that dependences of the band-gap energy and the luminescence peak position on the Zn content in CIZS thin films changed nonlinearly and had the minimal value at the Zn concentration about 2.5 - 3.0 at. %.
