摘要
Abstract
The content and distribution of niobium, crystal structure and the characteristic peaks of chemical bond in the Nb: KTP crystals grown by flux and hydrothermal method were investigated by LA-ICP-MS, X-ray diffraction analysis, micro laser Raman spectroscopy. The effects of niobium doped and crystal growth methods on structure and Raman spectrum of Nb: KTP crystals were analyzed. The results show that the stoichiometry of potassium reduced as niobium doped content increasing in Nb: KTP crystals. The unit cell volume is under the control of synergistic reaction by blockage effect and expansion effect. The unit cell volume in crystals grown by flux method is bigger than those grown by hydrothermal method when the raw material mixture ratio is same, so the growth method could be distinguished by unit cell volume. The interaction of TiO6 octahedral and PO4 tetrahedral is changing after Nb entered crystal lattice, thus, a few of characteristic peaks are drift.关键词
