Abstract

Low-dimensional, lead-free, and cuprous-based halide compounds of Cs₃Cu₂Br₅ micro-rods and CsCuBr₂ micro-crosses (MCs) were synthesized via a simple solution method. The CsCuBr₂ MCs were quite stable in air. Distinct green electroluminescence at 527 nm originating from CsCuBr₂ MCs was observed at a low driving voltage of less than 3 V.
