Abstract:
Results related to investigation of X-ray induced luminescence spectra in ZnIn 2 S 4 , CdGa 2 S 4 and Zn 3 In 2 S 6 single crystals measured at 300 and 80 K are presented. The spectra mainly consist of one band with maximum at 1.67 and 1.97 eV (80 K), respectively, generated due to donor-acceptor recombination.
