本文报导经用液相电弧放电结合水热处理制备的Ａｇ修饰ＴｉＯ２锐钛矿相复合粒子呈现亚铃状纳米结构，并具有拉曼表面增强散射（ＳＥＲＳ）。随着ＡｇＴｉＯ２团簇复合粒子。平均尺寸的减少，增强效应趋于增加，最大增强因子可达８００。Ａｇ粒子表面等离子体激发的强电场产生ＴｉＯ２超细粒子新的光学响应。作者也发现该锐钛矿相在１４０ｃｍ－１处或许由无序引起的一个新的谱带，同时简要讨论了体系ＳＥＲＳ增强弱化的原因。
In this paper, the Ag modified TiO2 anatase phase composite particles prepared by liquid-phase arc discharge combined with hydrothermal treatment show sub-bell-shaped nanostructures and have Raman surface enhanced scattering (SERS). With Ag TiO 2 cluster composite particles. The reduction of the average size tends to increase the enhancement effect and the maximum enhancement factor can reach 800. New Optical Response of TiO2 Ultrafine Particle Produced by Strong Electric Field Excited by Plasmid Surface Plasmon. The authors also found that the anatase phase might be caused by disorder at 140cm-1, and also briefly discussed the reason why the SERS enhancement weakens.
