Abstract:

Magnesium gallate(MgGa2O4) is a kind of gallate with spinel structure,which is composed of magnesium oxide (MgO) and gallium oxide(Ga2O3).It has good dielectric properties,optical properties,radiation resistance and high tempera-ture stability etc..Due to the existence of a self-activated emission band in the blue visible light region,it has received exten-sive attention in luminescence research.The doping of rare earth and transition metal elements can change the energy transfer process,improve the luminescence efficiency and broaden the luminescence range,which can be applied in many fields such as display,illumination,medical diagnosis and laser,and it has broad application prospect.The research progress on the structure and optical properties of MgGa2O4 single doped and co-doped with metal elements such as chromium(Cr),cobalt(Co),manganese(Mn),dysprosium(Dy) and europium(Eu) in recent years was summarized,the main problems existing in the current researches were analyzed,and the research directions and development applications of MgGa2O4 doped with metal elements in the future were also prospected.

Key words: MgGa2O4, metal doping, optical property, research progress
