摘要：

Herein, we synthesized CH3NH3PbBr3 nanoparticles using succinic acid and oleylamine at a fixed ratio as ligands. The formed stable CH3NH3PbBr3 NCs exhibit narrow green photoluminescence with high quantum yield as compared to the perovskites formed through oleic acid. Moreover, a fluorescent keypad lock security device authorizing password entries was constructed based on the output emission signal. The fluorescent keypad lock could be unlocked upon entering the correct sequence of password, i.e. MPDSOC. Furthermore, characterizations and morphology studies have been performed using UV, PL, XRD, TCSPC and TEM. In addition, stability tests were monitored using fluorescence spectra.
