eng	Phosphate glasses and their use as a matrix for the creation of glass ceramics	Phosphate glasses, characterized by their unique network structure of PO4 tetrahedra, exhibit distinct properties such as low melting temperatures, high thermal expansion coefficients, and good solubility for various metal oxides. These attributes make them promising candidates for glass ceramics, a versatile class of materials formed by controlled crystallization of glass. The potential applications of phosphate-based glass ceramics are broad, spanning biomedical fields due to their bioactivity and biocompatibility, to optical and electronic devices owing to their tunable refractive indices and electrical properties. Ongoing research focuses on optimizing parent glass matrix and controllable reproducible synthesis to enhance their performance and extend their use in advanced technological applications. In current research, we focus on the incorporation of metal halide perovskite materials from the CsPbBr3 family into phosphate glasses. The combination of CsPbBr3 and phosphate glasses in the development of glass ceramics is an area of significant interest due to the unique and complementary properties of these materials. CsPbBr3, a perovskite compound, is known for its exceptional optoelectronic properties, including high photoluminescence quantum yields, tunable emission wavelengths, and excellent charge carrier mobility. Integrating CsPbBr3 into phosphate glasses to form glass ceramics can enhance these properties while benefiting from the structural and thermal advantages of the glass matrix. Phosphate glasses serve as an excellent host material due to their low melting points, high thermal expansion coefficients, and good solubility for various metal oxides, including those used in perovskite compositions. The incorporation of CsPbBr3 into phosphate glass matrices through controlled crystallization can lead to the formation of nanocrystals within the glass, creating a composite material that combines the mechanical and chemical stability of the glass with the
