Lead phosphate glasses containing Eu(3+) and Dy(3+) have been studied. Local structure was verified using Fourier transform (FT)-IR spectroscopy. Emission bands of Eu(3+) and Dy(3+) ions in lead phosphate glasses are observed in the visible spectral range, which correspond to 5D0→7F(J) (J=0,1,2,4) and 4F(9/2)→6H(J/2) (J=15,13,11) transitions, respectively. Shorter luminescence decays from excited states of Eu(3+) and Dy(3+0 are due to the presence of PbO in phosphate glass.
研究了含有 Eu(3+)和 Dy(3+)的磷酸铅玻璃。利用傅里叶变换（FT）-红外光谱法验证了局部结构。在可见光谱范围内观察到磷酸铅玻璃中 Eu(3+)和 Dy(3+)离子的发射带，分别对应于 5D0→7F(J)（J=0、1、2、4）和 4F(9/2)→6H(J/2)（J=15、13、11）跃迁。Eu(3+)和 Dy(3+)的激发态的荧光衰减较短，这是由于磷酸铅玻璃中存在 PbO。
