[Temperature-dependence emission properties of Eu(3+)-doped in LiNbO3 single crystal].
The temperature-dependence emission spectra of lower and upper part of Eu(3+) -doped LiNbO3 crystals from 77 to 600 K were investigated under the excitation of a 488 nm light. The results show that, for upper part of crystal, the fluorescence intensity of Eu3+ ions increases with the temperature increase, however, for lower part, the intensity first increases with the temperature increase, and then decreases obviously with temperature increase. The variations of fluorescence intensity for lower and upper part of crystals are explained. The emission intensity of Eu3+ ions in LN is the total effect of thermally excited emission, phonon-assistant absorption and temperature-quenching effect.
