Reversible light-modulated photoiuminescence from azobenzene-impregnated porous silicon

摘要

Azobenzene-impregnated porous silicon (azo-PS) was used, for the first time, as a color-rewritable organic/Inorganic hybrid material. Under UV light illumination, the generation of c/s-azo enhances the red photoiuminescence (PL) emission. Images can be written and erased under external light and thermal stimuli.
