Abstract
A core/shell semiconductor nanoparticle structure comprises a core comprising a halide perovskite semiconductor and a shell comprising a semiconductor material that is not a halide perovskite (and that is substantially free of halide perovskites). The halide perovskite semiconductor core may be of the form AMX, wherein: A is an organic ammonium such as CHNH, (CH)(CHNH), PhCHNH, CHCHNHor 1-adamantyl methyl ammonium, an amidinium such as CH(NH), or an alkali metal cation such as Li, Na, K, Rbor Cs; M is a divalent metal cation such as Mg, Mn, Ni, Co, Pb, Sn, Zn, Ge, Eu, Cuor Cd; and X is a halide anion (F, Cl, Br, I) or a combination of halide anions.
