摘要：Europium-doped borophosphate glasses were prepared by the melt quenching method for application in light-emitting diodes. Emission spectra and electron paramagnetic resonance were studied for the glass samples. The relative intensity ratio of Eu2+ to Eu3+ emissions is composition dependent, especially the B2O3/P2O5 (B/P) ratio and the type of alkaline earth cations. The possible mechanisms are discussed.
