Precipitation and Optical Properties of CsPbBr₃ Quantum Dots in Phosphate Glasses

Abstract

CsPbBr3 quantum dots were precipitated in phosphate glasses through heat treatment. Controlled formation of CsPbBr3 quantum dots was realized by adjustment of heat‐treatment conditions. Absorption and photoluminescence spectra of CsPbBr3 quantum dots were tuned from 432 to 521 nm. Upon ultraviolet or blue light excitation, efficient photoluminescence from these CsPbBr3 quantum dots doped phosphate glasses was observed.

Glass Ceramic Phosphors: Towards Long‐Lifetime High‐Power White Light‐Emitting‐Diode Applications–A Review

“…Undoubtedly, introducing these phosphors into all‐inorganic glass matrix to form GC can greatly improve their physical/chemical stability. Recently, β ‐Sialon:Eu 2+ or perovskite QDs embedded GCs, exhibiting narrow full‐width at half‐maximum (FWHM), have been announced; unfortunately their applications for backlight display have not received sufficient attentions yet. There should be more work to be done on this topic.…”

Light Generation in Lead Halide Perovskite Nanocrystals: LEDs, Color Converters, Lasers, and Other Applications

“…[9] Most LHP-NCs can be synthesized through a facile solution reaction, e.g., ligand-assisted reprecipitation in an ambient environment and hot injection in a nitrogen atmosphere, followed by dispersion in a low dielectric constant solvent, e.g., toluene, to form a homogeneous colloidal solution. [31][32][33][34][35][36][37][38][39] In situ antisolvent processing is another technique that can be used to fabricate high-quality LHP-NCs, mostly in the form of solid thin films, using precursor solutions. [40][41][42][43] First, a rough introduction of the fundamental properties of LHP-NCs is presented for a better understanding.…”

Silver nanoparticles enhanced luminescence and stability of CsPbBr3 perovskite quantum dots in borosilicate glass

“…Recently, the incorporation of CsPbX 3 QDs into glass has attracted widespread attention. According to Bing Ai et al, the CsPbBr 3 quantum dots were successfully precipitated in a phosphate glass system by conventional high temperature, solid phase, and heat treatment methods . Glass coating significantly improves the stability of CsPbBr 3 quantum dots, and perovskite quantum dots still exhibit excellent optical properties inside the glass …”
