| description | Glass matrix embedding is an efficient way to improve the chemical and thermal stability of the halide perovskite QDs. However, CsPbX<sub>3</sub> QDs exhibit distinct optical properties in different glass matrixes, including photoluminescence (PL) peak position, PL peak width, and optical band gap. In this work, the temperature-dependent PL spectra, absorption spectra, high-energy X-ray structure factor <i>S</i>(<i>Q</i>), and pair distribution function (PDF) were integrated to analyze the structural evolution of CsPbBr<sub>3</sub> QDs in different glass matrixes. The results show that the lattice parameters and atomic spacing of CsPbBr<sub>3</sub> QDs are affected by the glass composition in which they are embedded. The most possibility can be attributed to the thermal expansion mismatch between CsPbBr<sub>3</sub> QDs and the glass matrix. The results may provide a new way to understand the effect of the glass composition on the optical properties of CsPbBr<sub>3</sub> QDs in a glass matrix. |
