摘　　要：等离子体激子诱导光催化反应在可控性和选择性方面具有相当大的潜力。在Au/石墨烯/SiO_(2)/Si复合基底上,借助拉曼指纹谱的优势,基于表面等离子体驱动光催化反应,实现微米尺度下信息加密图案化读写的一个实质性应用。采用532 nm波长的激发光进行图案的绘制,785 nm波长的激发光进行Mapping读取,实现了二维加密图形的可控绘制和读取。通过构建纠错公式,进行纠错Mapping成像,即扣除由于石墨烯基底本身不均匀导致的增强和光催化效果的不同,从而进行加密信息字符的纠错,实现了更好的加密信息读取效果。Plasma exciton induced photocatalytic reactions have considerable potential in terms of controllability and selectivity.On an Au/graphene/SiO_(2)/Si composite substrate,utilizing the advantages of Raman fingerprint spectroscopy,a substantial application of information encryption patterned reading and writing at the micrometer scale is achieved through surface plasmon driven photocatalytic reactions.Using excitation light with a wavelength of 532 nm for pattern drawing and excitation light with a wavelength of 785 nm for Mapping reading,controllable drawing and reading of twodimensional encrypted graphics have been achieved.By constructing an error correction formula and performing error correction Mapping imaging,the enhancement and photocatalytic effects caused by the non-uniformity of the graphene substrate are deducted,thereby correcting encrypted information characters and achieving better encrypted information reading effects.
