    • Abstract
  • CsPbBr3/CMS-Na composites were synthesized by in-situ growth method for the first time. The crystal structure, morphology and luminescence properties of the samples were characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy and fluorescence spectrophotometer. The results show that the photoluminescence spectra of CsPbBr3/CMS-Na composites behave an ordered blue-shift of 518 to 502 nm. The fluorescence intensity is significantly increased, and the green light emission is brightest when the mass ratio of CsPbBr3 to CMS-Na is 1 ∶ 2. The CsPbBr3/CMS-Na composites show excellent stability, remaining 67.6% of the initial brightness after 21 d in air. The results have potential application value for CsPbBr3 quantum dots in the field of lighting and display.
