Dopant effect on the optical and thermal properties of the 2D organic–inorganic hybrid perovskite (HDA)2PbBr4

Three metal ions (Mn 2+ , Sb 3+ , and Bi 3+ ) were successfully doped into the 2D lead-based perovskite (HDA) 2 PbBr 4 , in which the dopant effects on the optical and thermal properties are studied.
