SrS crystals were grown from SrS–Sb 2 Te 3 solutions at 1050 °C. Its structural and compositional analysis showed that solution‐grown SrS has a cubic structure and contains 0.06 at% of Sb and 0.03 at% of Te, respectively. Comparison of room‐temperature (RT) cathodoluminescence (CL), selectively excited 77 K and RT photoluminescence (PL), and 77 K PL excitation (PLE) spectra of the grown SrS with those of SrS:Te and SrS:Sb showed the existence of two kinds of luminescent centers, Te isoelectronic‐trap centers and a Tl‐type Sb 3+ center.
