Research Progress on Silicon-based Luminescent Glass and Preparation Techniques

Due to high transmittance, excellent chemical stability, ease of machining, and other advantages, silicon-based oxide glass is considered to be an ideal matrix material. By introducing different lighting dopants, the optical glass with different properties has been widely used in many fields. However, the preparation technologies of the optical glass are facing new challenges because of these volatile and unstable lighting dopants which easy to be decomposed. This review introduces the development status and the preparation techniques of the silicon-based light-emitting glass containing bismuth ions, quantum dots and phosphors. By comparing the melting method, Sol-Gel, solid-state sintering and spark plasma sintering (SPS), the research progress and superiority of SPS technology applied in optical glass preparation are focused on and the developments of this new preparation technology are also reviewed.
