[22p-P08-9] Investigation of properties in Cu2Sn1-xGexS3 by observation of photoluminescence
Keywords:Cu2Sn1-xGexS3, CTGS, photoluminescence
We investigated the excitation intensity dependence and temperature dependence of Cu2Sn1-xGexS3 photoluminescence spectra with different Ge contents.
As the Ge content increased, the peak of wide luminescence shifted to the high energy side.
Exciton emission was observed on the higher energy side in the sample with the highest Ge content.
