摘要：A series of Eu ion-doped aluminoborosilicate glasses was prepared by melt-quenching method and characterized by spectroscopic techniques, including Fourier transform infrared (FTIR), absorption, photoluminescence (PL), and electron paramagnetic resonance (EPR). The FTIR spectra showed that various glass structures formed when Al2O3 was partially replaced by B2O3. The PL characterization revealed that the emission intensity of Eu2+ ions firstly increased and then decreased with an increasing amount of Al2O3 replaced by B 2O3. Meanwhile, the emission intensity ratio of [Eu 2+]/[Eu3+] also followed the same trend. The EPR spectra confirmed the concentration variation of Eu2+ ions in the glass samples, which agreed well with the PL results. The possible mechanism of the effect of the glass network structure on the reduction behavior of Eu ions is discussed. ? 2010 Elsevier B.V. All rights reserved.
