Research Progress of Rare Earth Doped Glasses with the Blue and Green Upconversion Fluorescence

Recently, upconversion glass fiber laser, which can be applied in the fields of color display, optical data storage, biomedical diagnostics and undersea optical transmission, had been widely concerned. In this paper, developments of upconversion luminescence in rare earth doped glasses were reviewed briefly. Kinds of rare earth ions emitting blue and green fluorescence in the visible band were generalized. The research progresses of upconversion emission properties from different host glasses (such as fluoride glasses, sulphide glasses, tellurite glasses, germanate glasses, bismuthate glasses and oxyhalide glasses) in recent years were introduced detailedly. In the end, the research trend of upconversion emission of rare earth ions doped glasses was proposed.
