CH₃NH₃PbBr₃ nanoplatelets were synthesized via a hot-injection method. Red shift from 451 to 531 nm of the photoluminescence (PL) spectrum was found after different folds of dilution. The results of TEM and XRD show that red shift is caused by the growth of particles for the aggregation self-assembly of CH₃NH₃PbBr₃ nanoplatelets. The contrast experiments prove that oleylamine plays an important part in the aggregation self-assembly of nanoplatelets. The aggregation self-assembly mechanism of CH₃NH₃PbBr₃ nanoplatelets is elaborated combining the results of XRD and TEM.
