The encapsulation of colloidal lead halide perovskite nanocrystals within silica (SiO2) is one of the strategies to protect them from polar solvents and other external factors. Here, we demonstrate the overcoating of CsPbBr3 perovskite nanocrystals with silica by exploiting the anhydride-induced transformation of Cs4PbBr6 nanocrystals....

We have approached the synthesis of colloidal InAs nanocrystals(NCs) using amino-As and ligands that are different from the commonlyemployed oleylamine (OA). We found that carboxylic and phosphonicacids led only to oxides, whereas tri-n-octylphosphine,dioctylamine, or trioctylamine (TOA), when employed as the sole ligands,yielded InAs NCs with...

Various strategies have been proposed to engineer the band gap of metal halide perovskite nanocrystals (NCs) while preserving their structure and composition and thus ensuring spectral stability of the emission color. An aspect that has only been marginally investigated is how the type of surface passivation influences the structural/color...
