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 Eu 2+ to Eu 3+ emissions is composition dependent, especially the B 2 O 3 /P 2 O 5 (B/P) ratio and the type of alkaline earth cations. The possible mechanisms are discussed.
