摘　　要：实验测量外加电场对 Ｓｎ Ｏ２ 纳米晶簇室温近紫外光吸收的影响程度，得到光吸收变化谱线和光吸收大小变化随外加电场变化曲线。它们均为一种非线性变化规律，在高电场区。The effect of external electric field on optical absorptions in near UV wavelength region in SnO 2 nanoclusters is determined at room temperature.The absorption spectra and absorbance variations with the applied field are obtained,which exhibits non-linearity and is saturated at high field region.
