Lead-free Mn-doped antimony halide perovskite quantum dots with bright deep-red emission

We reported the first synthesis of Mn2+ doped Cs3Sb2Clx/Br9-x (0 <= x <= 9) perovskite quantum dots (PQDs) by regulating the coprecipitation of Mn2+ and Sb3+ with thiol ligands. These lead-free PQDs demonstrated bright photoluminescence emission centered at 660 nm and a high quantum yield of similar to 49%, making them suitable for optical applications.
