Controlled synthesis of brightly fluorescent CH₃NH₃PbBr₃ perovskite nanocrystals employing Pb(C₁₇H₃₃COO)₂ as the sole lead source.

ABSTRACT: Organometal halide perovskite nanocrystals hold vast potential for application in photovoltaics, light emitting diodes, low-threshold lasers, and photodetectors due to their size-tunable bandgap energies and photoluminescence as well as excellent electron and hole mobilities. However, the synthesis of such nanocrystals typically suffers from poor structural stability in solution and the coexistence of lamellate nanocrystals (nanoplatelets) and spherical nanocrystals (nanoparticles). Here we show that the pure nanoparticle morphology of CH₃NH₃PbBr₃ nanocrystals can be realized by employing lead oleate (Pb(C₁₇H₃₃COO)₂) as the sole lead source and controlled using short- and long-chain mixed alkyl ammonium. These nanocrystals a
