Highly emissive Sb3+-doped 0D cesium indium chloride nanocrystals with switchable photoluminescence

All-inorganic lead-free luminescent metal halide nanocrystals (NCs) are very important in optoelectronics, but their applications are limited by the low photoluminescence (PL) efficiency. It is an effective approach via ns2-metal ions doping for tailoring the optical properties of metal halide NCs and expanding their applications.
