摘要：

Raman spectra of LiNbO3 crystals with different hydrogen-ion-exchanged time were examined. E(TO) and A(1)(TO) modes appear gradually in the transverse A(1)- and E- symmetry spectra respectively with increasing the exchange time and the dependence of their intensities on the exchange time is also observed. We attribute these results to both the internal strains resulting from the ordering-disordering distribution of H ions in the sample and the enhanced photorefractive effect.
