"Visible Light Communication (VLC)" is the best candidate for the next generation of network communication owing to its wide bandwidthscompatibility with solid-state lighting devices. Our proposed technology features a novel multilevel photosensing memory which can integrate the photosensing, memorycomputation components for VLC into one device. This device is based on a thin film transistor, where the oxide semiconductor is added with gold nanoparticles to form a "co-active layer" in order to expand the visible light sensing spectrumefficiently convert the light signal into a current signal. It not only simplifies the production processreduces the cost, but also accelerates the signal transmission speed, which further advances the future mobile comm

Inorganic porous nanofibers with surfaceinterface defects are prepared through humidity-controlled electrospinninghigh-temperature annealing technology. Under the irradiation of light sources of different wavelengths (380~780 nm), the bound electrons stored in the valence band can be excited to the conduction band to form free electrons on the surface of the material, generating different intensities of microcurrents, light sensitivitymicrocurrent changes. Because the "inorganic nanofiber" technology has high uniquenesshigh product compatibility, it can be applied to a wide range of markets.
