- Abstract
Plasma exciton induced photocatalytic reactions have considerable potential in terms of controllability and selectivity. On an Au/graphene/SiO2/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.
