| 中文摘要: |
| 把主体材料聚甲基丙烯酸甲酯（PMMA）和客体偶氮化合物,用溶胶-凝胶法制成溶胶,旋涂成膜,测量了其紫外-可见吸收光谱和厚度。用电晕极化的方法对薄膜进行极化,然后实时监测了不同温度和不同厚度下薄膜的二次谐波产生（SHG）强度随时间退极化的特性。利用双指数函数拟合其驰豫曲线,结果表明,对于厚度相同的偶氮薄膜,随温度的升高其平均驰豫时间变短;而相同温度下不同厚度的薄膜,平均弛豫时间随厚度增加而增加。 |

| The PMMA doped azo-dye compound films were prepared by the spin coating method.Their thickness and UV-Vis absorption spectra were measured.The films were poled by the corona poling method Furthermore,the second harmonic generation relaxation progress were monitored at different temperatures and different film thickness.The relaxation curve which were measured by experimental were fitted with the double exponential function.The fitting results show that for the films with the same thickness,the average relax... |
