We present the Raman and photoluminescence (PL) spectra of CuGaS 2 : Cd grown by iodine transport method. The PL spectra of CuGaS 2 showed both band gap and deep center emission, while for CuGaS 2 : Cd the deep center emission was suppressed completely and a new strong emission at 2.31 eV with an ac
