Room temperature synthesis and characterization of novel lead-free double perovskite nanocrystals with a stable and broadband emission

Low-dimensional and lead-free halide perovskites are of great interest for their wide application potential for optoelectronic applications. We report on the successful synthesis of novel lead-free colloidal Cs3BiBr6 nanocrystals (NCs) with an ultra-small size of ∼1.5–3 nm by a room temperature anti...
