摘要：

White light emission of rare earth (RE)-free Mn-doped SnO-ZnO-P2O5 glass is demonstrated. Glass transition temperature of the obtained glass is below 440 degrees C, which assures the application to sealant of solid state light emitting devices. The RE-free transparent glass shows white light emission with a high value of quantum efficiency (QE) comparable to conventional crystalline phosphor by excitation of deep UV light. The broad emission of RE-free transparent glass can be continuously tuned by both the amount of activator and the composition of the glass without decrease of the QE value.
