摘　　要：A series of Tb-doped solid solutions PbGd1-xTbxB7O（13）（x = 0~1） were synthesized by high-temperature solid state reaction method. The luminescence properties were investigated under UV（274 nm） and near-UV（372 nm） excitation. The emission spectrum by 274 nm exciting reveals a charge-transfer between Gd^（3＋） and Tb^（3＋） ions. Under near-UV light（372 nm） excitation, PbGd1-xTbxB7O（13）：x Tb~（^（3＋）） exhibits intense green emission centered at 543 nm due to the ~5D4→~7F5 transition of Tb^（3＋） activator. The optimum doping concentrations were found to be x = 0.8 with the quantum efficiency of 35%. One may expect that PbGd1-xTbxB7O（13） has the potential to be used as a green phosphor activated by near near-UV light.A series of Tb-doped solid solutions PbGd1-xTbxB7O（13）（x = 0~1） were synthesized by high-temperature solid state reaction method.
