摘要

采用熔融冷却法制备了铕掺杂碱土金属硼铋酸盐玻璃（BBME'BBCE'BBSE'BBBE）。研究了玻璃的密度、摩尔体积、光学碱度等物理性质'分析了玻璃的结构、光学性质和热稳定性。结果表明'从BBME到BBBE'玻璃结构致密程度不断下降。Eu

能较好地熔融到玻璃中'成为良好的发光中心'在465 nm和613 nm处分别有强烈的蓝光激发和橙红光发射'激发和发射强度从BBME到BBBE不断增强。玻璃均呈现非晶态'其结构对称性相对较低'从BBME到BBBE呈下降趋势。玻璃结构主要组成为非对称的[BO

]三角体、松散的[BO

]四面体、[BiO

]三角体以及含[BO

]四面体的三硼环、四硼环和五硼环'结构中均不存在硼六圆环'也不存在含[BO

]三角体的五硼环、焦硼环和正硼环。研究结果表明'所研制的低温铕掺杂碱土金属硼铋酸盐玻璃具有热稳定好、折射率相对适宜的优点'有望成为未来白光LED（荧光粉）玻璃陶瓷的良好基质。

Abstract

doped alkaline earth bismuth borate glasses(BBME

BBCE

BBSE

BBBE)were prepared by the rapid melt quenching technique. The general physical properties including density

molar volume

optical basicity and so on were studied

the structure

optical properties as well as thermal stability of the glasses were investigated. The tightness of the glass decreases from BBME to BBBE. Eu

melts homogeneously in the glasses and acts as a well activator. The intense emission peaked at 613 nm is observed in the emission spectra under 465 nm excitation. the intensity increases gradually from BBME to BBBE. All the glass samples present amorphous states and have low symmetric structure

and the symmetries decrease from BBME to BBBE. The asymmetric[BO

] units

loose[BO

] units

[BiO

] units and tri-

tetra-

penta-borate groups including[BO

] units are identified in the glass samples

however

six member rings and penta-borate

pyro-borate

ortho-borate groups consisting of[BO

] are not observed. The glass samples with well thermal stability

low melting temperature and appropriate refractive index are expected to be good candidates applied for WLED glass ceramic in the future.
