Abstract :
We have systematically investigated the optical properties of isoelectronic centers (IECs) of ZnSTe in the whole composition range from ZnS to ZnTe. In the S-rich ZnSTe photoluminescence is dominated by Te-bound excitons, while in Te-rich side, S-related bound exciton emission dominates the radiative recombination. Localization nature of IEC bound exciton emissions in both S-rich and Te-rich side ZnSTe alloys are studied in detail.
