采用熔融猝灭法制备了一系列掺Eu离子的铝硼硅酸盐玻璃，并用傅立叶变换红外光谱(FTIR)、吸收光谱、光致发光(PL)和电子顺磁共振(EPR)等光谱技术对其进行了表征。傅立叶变换红外光谱表明，当B_2O_3部分取代Al_2O_3时，形成了多种玻璃结构。光致发光表征表明，Eu2+离子的发射强度随B2O3取代Al2+量的增加而先增大后减小。同时，[Eu2+]/[Eu3+]的发射强度比也遵循相同的趋势。EPR谱证实了Eu2+离子在玻璃样品中的浓度变化，与荧光光谱结果吻合较好。讨论了玻璃网络结构对Eu离子还原行为影响的可能机制。(C)2010爱思唯尔B.V.保留所有权利。
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 B2O3. Meanwhile, the emission intensity ratio of [Eu2+]/[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. (C) 2010 Elsevier B.V. All rights reserved.
