Boosting the broadband orange emission in organic–inorganic hybrid (DPG)₃InBr₆via antimony doping

(DPG) 3 InBr 6 has two emission bands located at 470 and 630 nm. After Sb 3+ doping, the weak high energy emission disappears which is derived from its energy transfer to low energy state. Inset: the synthesized single crystal photo under daylight and UV-365 nm.
