CsPbX3/PMMA发光透明纳米复合材料的制备及其表征
Preparation and characterization of luminescent CsPbX3/PMMA transparent nanocomposites
摘要
Abstract
This paper focuses on two key challenges faced by cesium halide lead perovskite quantum dots(CsPbX3,X=Cl,Br,I)in optoelectronic device applications:lead toxicity and insufficient stability.To address these issues,bulk nanocomposites were prepared using hydrophobic CsPbX3(X=Cl,Br,I)nanoparticles as fillers and poly(methyl methacrylate)(PMMA)as the matrix via in-situ photopolymerization.The PMMA protective layer effectively prevents lead ion leaching and significantly enhances the optical stability of CsPbX3.The oleic acid-stabilized CsPbX3 nanoparticles and their CsPbX3/PMMA composites were systematically characterized using X-ray diffraction(XRD),transmission electron microscopy(TEM),UV-vis transmission spectroscopy,and photoluminescence spectroscopy.The results indicate that the CsPbX3/PMMA nanocomposites exhibit high transparency in the visible region and emit blue(X=Cl),green(X=Br),and red(X=I)light under UV lamp(365 nm)excitation.After 11 d of storage in a natural environment,the luminescence intensity decay of the nanocomposites decreased by 50%less than that of pure CsPbX3 quantum dots,demonstrating their highly efficient luminescence,enhanced stability,environmental friendliness,and promising application potential.关键词
