【摘要】 利用FLN技术,测定了Eu³⁺离子在镧磷酸盐玻璃中的选位光谱。激发源为闪光灯泵可调谐若丹明染科激光器。在实验中得到了四种主要的具有残留不均匀增宽的选位光谱。做了这些选位光谱与在77K测定的⁵D_o～⁷F₁跃迁的常规光谱轮廓之间的拟合,得到了满意的结果。更多还原

【Abstract】 Site-selective spectra of Eu3+ ions in the La-phosphate glass were measured using laser-induced fluorescence linenarrowing technique. The excitation source was a flashlamp pumped Rhodamine tunable dye laser. In the experiment four main kinds of site-selective spectra with the remains of inhomogeneously broadening were obtained. These site-selective spectra fit to conventional spectrum measured at 77K for 5D0-7F1 transition of Eu3+, and favourable result has been obtained.更多还原
