title: Homogeneous Synthesis and Electroluminescence Device of Highly Luminescent CsPbBr3Perovskite Nanocrystals.
abstract: Highly luminescent CsPbBr3perovskite nanocrystals (PNCs) are homogeneously synthesized by mixing toluene solutions of PbBr2and cesium oleate at room temperature in open air. We found that PbBr2can be easily dissolved in nonpolar toluene in the presence of tetraoctylammonium bromide, which allows us to homogeneously prepare CsPbBr3perovskite quantum dots and prevents the use of harmful polar organic solvents, such as N,N-dimethylformamide, dimethyl sulfoxide, and N-methyl-2-pyrrolidone. Additionally, this method can be extended to synthesize highly luminescent CH3NH3PbBr3perovskite quantum dots. An electroluminescence device with a maximal luminance of 110 cd/m2has been fabricated by using high-quality CsPbBr3PNCs as the emitting layer.
