| 摘 要： | 光致变色材料具有光子型反应的特点,控制光致变色材料吸收的光子数就可以控制材料的反应程度,从而实现多阶存储。根据光化学反应的原理,分析了光致变色材料的写入过程,建立了光致变色多阶存储写入过程的反射率模型。根据该模型的仿真计算结果,设定了一组合适的曝光量,在1,2_双(2_甲基_5_(4_(1,3_二氧戊环基)苯基)噻吩_3_基)全氟环戊烯材料上实现了8阶存储。

| Abstract: | Photochromic materials have the photon-reaction feature.If the number of photons absorbed by the material is controlled,the reaction degree of the material is controlled.Thus the multi-level storage was realized.The write process of photochromic materials was analyzed,and a model was built based on the photochemistry principles.Following the simulation results of the model,a set of exposure energy values are used on 1,2-bis(2-methyl-5-(4-(1,3 -dioxacyclohex) benzene) thiophen-3-yl) perfluorocyclopentene material.And 8 level storage is realized. |
