TY - JOUR AU - ZHANG, Lisheng AU - LIU, Ruilin AU - WANG, Xueyan PY - 2024 TI - Research on Raman spectral information encryption and error correction based on photocatalytic reaction JO - Journal of Capital Normal University (Natural Science Edition) SN - 1004-9398 SP - 124 EP - 130 VL - 45 IS - 2 AB - 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 two-dimensional 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.
