Energy transfer and photoluminescence properties in Bi3+ and Eu3+ co-doped ZnGa2O4
A series of single phase Bi3+/Eu3+ co-doped ZnGa2O4 phosphors were prepared by high temperature solid state reaction and their luminescence properties were investigated. The Bi3+/Eu3+ co-doped ZnGa2O4 phosphor exhibited an intense broad blue light emission located at 430 nm from Bi3+ and a narrow red emission at 616 nm form Eu3+. Energy transfer from Bi3+ to Eu3+ was observed in the ZnGa2O4 host matrix. The color tunbility of Bi3+/Eu3+ co-doped ZnGa2O4 phosphor can be obtained by changing the Eu3+ concentration, which indicates that color tunable Bi3+/Eu3+ co-doped ZnGa2O4 phosphor has a potential application in light emitting diodes. Additionally, the blue long persistent luminescence of ZnGa2O4:Bi3+ phosphor was obtained.
