稀土离子掺杂钠钙硅玻璃的光学性能和光谱特性

Optical Properties and Spectral Characteristics of Soda Lime Glass Doped with Rare Earth Elements

通过分光光度计和荧光光谱仪分别测试了几种稀土离子在钠钙硅玻璃中的光学性能和光谱特性,总结了不同稀土离子的吸收峰、发射峰及对应的能级跃迁。结果表明:Ce、Sm、Eu、Tb和Dy 5种稀土离子吸收紫外光并发射可见荧光;Sm、Dy和Yb 3种稀土离子吸收近红外光。

The optical properties and spectral characteristics of soda lime glasses doped with rare earth elements were measured by spectrophotometer and fluorescence spectrometer. The absorption and emis- sion peaks and corresponding energy level transition due to doped various rare earth elements were in- vestigated. The results showed that Ce, Sm, Eu, Tb, Dy ions absorb UV light and emit visible light, whereas, Sm,Dy,Yb ions absorb NIR, and all of these ions almost do not absorb visible light.
