An optical study was made of screen-printed material. Photoluminescence and excitation spectroscopic data revealed the existence of a new defect center. The data were also very similar to those which corresponded to 2 complexes that were to be found in Cu-doped GaP, and to a Ag-related complex in Ag-doped ZnTe. It was concluded that the present defect was an iso-electronic complex involving Cl. That is, [VCd2ClTe].
