Abstract
We report an investigation of the CSn-center luminescent properties in the 2H SnS2 polytype over a wide temperature range. It is shown that in the temperature range from 5 to 200 K, the emission spectrum can be described in terms of the interaction of an electronic transition in the region of 1.4 eV with a localized phonon mode, whose frequency is 270 cm‒1. At temperatures exceeding 200 K, structural rearrangement of the center is observed, which manifests itself in qualitative changes in the emission spectrum and luminescence quantum yield.
