    • Abstract


      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 $^{5}D_{0} \rightarrow ^{7}F_{1,2}$ emission spectra have been measured under resonant excitation to the $^{5}D_{0}$ level at different wavelengths within the $^{7}F_{0} \rightarrow ^{5}D_{0}$ band at 16 K. Using the Stark level positions of the $^{7}F_{1}$ and $^{7}F_{2}$ 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.
