Abstract
ZnO films deposited on silicon porous substrates (PS) were prepared by electro-deposition
anodization on n type (100) silicon wafer. This ZnO/PS structure combines substrates having
specific structural and optical properties (IR emission), with nano-composites of ZnO
potentially interesting due to their functional properties (UV emission) to be integrated as
constitutive elements of devices in various optoelectronic applications mainly in blue light
emitters. With this combined structure, the blue shift in the PL peak is possible and easy to
obtain (467nm). the structural properties characterized by X-ray diffraction (DRX) and
scanning electronic microscopy (MEB).
