摘要

A TiO_2/porous silicon(PS) composite system is prepared by chemical vapor deposition.The crystal form with anatase phase of the samples is evaluated by X-ray diffraction and ultraviolet-visible(UV-vis) absorbance spectra,and the morphology with microsphere of TiO_2 particles is characterized by scanning electron microscopy.The composite system formed by this technique gives a broad blue luminescence and the mechanism of photoluminescence with TiO_2/PS is also discussed.
