What is Tuning the structural and photophysical behaviour of non-toxic CsSnCl3 using reduced graphene oxide for optoelectronic applications about?

The non-toxic metal halide-based perovskite materials can be a greener alternative to leadbased perovskites because of their stability and high-scale production. Herein, we have tuned the structural and photophysical behaviour of non-toxic halide-based perovskite CsSnCl3 by forming a heterostructure with reduced graphene oxide (rGO) owing to its high carrier mobility and thermal conductivity. The crystal structure of CsSnCl3 and CsSnCl3/rGO heterostructure has been analyzed using the X-ray diffraction (XRD) technique which confirms the formation of a highly crystalline cubic phase. The high absorption behaviour of CsSnCl3 and CsSnCl3/rGO can be clearly seen from the ultraviolet-visible (UV-vis) spectrum. A direct bandgap of 3.24 eV and 3.19 eV has been calculated from the Tauc plot for CsSnCl3 and CsSnCl3/rGO heterostructure respectively. The Photoluminescence (PL) plot shows a high quenching blue shift phenomenon in CsSnCl3/rGO heterostructure as compared to pristine CsSnCl3 material due to the faster separation and transfer of charges from photogenerated electron-hole pairs. Further, the surface morphology of CsSnCl3 and rGO/CsSnCl3 heterostructure has been noticed by utilizing t
