Glass and glass ceramics, as important optical functional materials, have significant applications in display, lighting, scintillator, laser and optical fiber amplifier. Titanium dioxide has high refractive index and high dielectric coefficient. Research shows that glass containing titanium dioxide can improve the luminescent properties of rare earth , and glass-ceramics can not only improve the luminescent intensity of rare earth, but also is a new material with scintillation properties. In this paper, This paper summarizes the preparation methods of titanium containing glass, including high temperature melt quenching, sol-gel process and aerodynamic levitation method，Which aerodynamic levitation method provides a new way for the preparation of high titanium glass. The structure and properties of Ti containing glasses and ceramics, such as the coordination of Ti, phonon energy and thermal properties of glasses, are briefly introduced. the research progress of radiation relaxation luminescence and scintillation luminescence of glass and glass ceramics titanium containing was investigated in recent years. Finally, the existing problems and future development trend of glass and ceramics are discussed titanium containing. It is believed that the glass and glass- ceramics containing TiO2 are expected to become the research hotspot of new materials for optoelectronic applications.
