Site-selective spectra of Eu3+ ions in the La-phosphate glass were measured using laser-induced fluorescence linenarrowing technique. The excitation source was a flashlamp pumped Rhodamine tunable dye laser. In the experiment four main kinds of site-selective spectra with the remains of inhomogeneously broadening were obtained. These site-selective spectra fit to conventional spectrum measured at 77K for 5D0-7F1 transition of Eu3+, and favourable result has been obtained.
