Article Synopsis
- Lead-free perovskite nanocrystals are appealing for their nontoxicity and potential use in displays, but modifying their optical properties is challenging due to the complexities of exciton emissions.
- This study explores how doping silver-based double perovskite nanocrystals with Bi and Sb can enhance their photoluminescence quantum yield, revealing that the two dopants impact the optical properties in distinct ways due to differences in electronic levels and ionic sizes.
- The findings underscore the significance of ionic size and microstraining, particularly highlighting that Bi's larger size makes its optical properties more sensitive to doping concentration compared to Sb, suggesting ways to optimize these materials for future applications.
Lead-free double perovskites are studied as an optional replacement to lead halide perovskites in optoelectronic applications. Recently, double-perovskite materials in which two divalent lead cations are replaced with an Ag and a trivalent cation have been demonstrated. The presence of a reactive silver cation and observations of metallic silver nanodecorations raised concerns regarding the stability and applicability of these materials.
