Luminescent Properties of the Jahn‒Teller Center in Carbon-Doped Tin Disulfide

We report an investigation of the C Sn -center luminescent properties in the 2H SnS 2 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...

Description
Summary:We report an investigation of the C Sn -center luminescent properties in the 2H SnS 2 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.
