简介：做铕的borosilicate眼镜被融化熄灭过程在空中准备。Eu2+和Eu3+的混合原子价被相片光光谱和电子识别顺磁的回声(EPR)。混合原子价的存在由于unequivalent替换和同样准备的borosilicate眼镜的de聚合网络被观察。在B2O3/BaO比率的玻璃作文的变化清楚地改变了Eu3+离子的稳定性。特别地，同样准备的borosilicate眼镜展出了易兴奋的系列在397，466和534nm集中了在约592和617nm给拓宽的橘子红排放的一盏tri波长灯，由于Eu3+离子的敏感过度的转变。这同时的tri波长刺激碰巧从钇铝柘榴石从近紫外的、蓝AlInGaN薄片和那与射出的波长相应:Ce3+。在466nm刺激下面的做Eu的眼镜的全部的量收益(QY)被评估是10%，潜在地向万用的联合提供做铕的borosilicate眼镜让红部件增加改进白光的质量。
