【摘要】 以PbF₂+GeO₂+WO₃+SiO₂+NaF为基质组份,双掺Yb³⁺/Er³⁺稀土离子,采用熔融技术,熔化温度为950℃,恒温20min,退火温度为380℃,恒温4h以上关炉,随炉降至室温,制得样品,采用Hatachi F4500型荧光光度计测试样品,激发波长为980nm,样品在550nm处呈现较强的发射峰,在528nm处有一个次发射峰,在680nm处有一个相对较弱的发射峰,并对上述结果进行了讨论分析,建立了该系统上转换发光机制。该样品具有化学稳定性好、机械强度高、激发谱带宽等优点,可做进一步开发应用。更多还原

【Abstract】 In this paper ,Yb3+/Er3+ doped glass ceramics was prepared in composition of PbF2+GeO2+WO3 + SiO2+NaF by melting method at 950 ℃ for 20 min following annealing at 380 ℃ for 4 h. The emission spectrum of the sample was measured by a Hatachi F4500 Flwore-spectrometer using a 980 nm laser excitation source . The emission spectrum shows a strong emission peak at 550 ran and weak peaks at 528 nm and 680 nm. The experimental results were discussed and the upconversion mechanism was established. The sample shows good chemical durability, mechamical strength and broad excitation spectrum. Therefore this glass ceramics can be developed for application.更多还原
