【 摘 要 】

A fluorophosphate laser glass doped with 1.0 mol% of Eu3+ ions has been prepared and studied by site-selective spectroscopy to explore the local structure of Eu3+ ions. Site-selective 5𝐷0 → 7𝐹1,2 emission spectra have been measured under resonant excitation to the 5𝐷0 level at different wavelengths within the 7𝐹0 → 5𝐷0 band at 16 K. Using the Stark level positions of the 7𝐹1 and 7𝐹2 levels, crystal-field analysis has been carried out. The results suggest the existence of a unique kind of site for all the environments of Eu3+ ions in this glass.
