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.
