摘要

采用熔淬法制备了掺杂银和镧系元素（Tm3+、Yb3+）的氟化氧玻璃。测量了玻璃在 350 至 550 纳米范围内的吸收，发现了银纳米团簇和 Tm3+ 转变的吸收边缘。在 300 至 500 纳米范围内的激发下，在 400 至 1100 纳米范围内检测了玻璃的光致发光光谱。光致发光激发光谱显示，Ag 纳米簇和 Tm3+ 离子可以有效地收集紫外范围的能量，并将其转换到可见光和红外（通过 Yb3+ 离子的发射）范围，从而使玻璃具有白光发射器和太阳光谱下转换器的前景。

Luminescence of silver, thulium and ytterbium doped oxyfluoride glasses

Silver and lanthanide (Tm3+, Yb3+) doped oxyfluoride glasses have been prepared by melt-quenching method. The absorption of the glasses was measured in the range from 350 to 550 nm revealing the absorption edges of Ag nanoclusters and Tm3+ transition. The photoluminescence spectra of the glasses were detected in the range from 400 to 1100 nm under excitation in the range from 300 to 500 nm. The photoluminescence excitation spectra showed that Ag nanoclusters and Tm3+ ions can effectively harvest energy in UV-range and convert to visible and infrared (through emission by Yb3+ ions) ranges making the glasses perspective as white light emitters and solar spectrum downconverters.

期刊介绍： Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
