Organic acid-regulated self-assembly and anti-oxidation of low-defect Sn-Pb perovskite nanocrystals toward optical anti-counterfeiting applications

Tin-lead mixed perovskite nanocrystals (NCs) attract extensive research interest for narrow bandgap and low toxicity, yet inherent surface defects, weak crystallinity and easy Sn 2+ oxidation severely degrade their stability and usability. This work adopts four organic acids (FA,...
