Abstract
- Lead-free copper halide perovskite nanocrystals (NCs) are emerging materials with excellent photoelectric properties. Herein, we present a colloidal synthesis route for orthorhombic Cs<subscript>2</subscript>CuCl<subscript>4</subscript> NCs with a well-defined cubic shape and an average diameter of 24 ± 2.1 nm. The Cs<subscript>2</subscript>CuCl<subscript>4</subscript> NCs exhibited bright, deep blue photoluminescence, which was attributed to the Cu(II) defects. In addition, passivating the Cs<subscript>2</subscript>CuCl<subscript>4</subscript> NCs by Ag<superscript>+</superscript> could effectively improve the photoluminescence quantum yield (PLQY) and environmental stability.
