Borosilicate glass has excellent chemical durability and remarkably low thermal expansion coefficient, which draws great attention to laboratory equipment and optical devices. In this chapter, the preparation process of borosilicate glass and transition process from gel to glass by sol–gel method are summarized in detail, especially, the factors for the preparation of transparent glass. Impressively, compared to pure glass material, transparent glass doped metal or semiconductor nanoparticles exhibit unique and excellent optical properties. Additionally, a series of quantum dots concluding sulfur, metal and oxides, and organic compounds quantum dots doped sodium borosilicate glasses are displayed. Finally, the relationship between microstructure and optical property is analyzed in depth.
