1 .Abstract
The Cu2O particles or clusters dispersed mesoporous posite films were prepared by a new method: First the matrix SiO2 films were prepared by sol-gel bined with the dip-coating technique, and then they were soaked in Cu(NO3)2 solutions followed by X-ray irradiation at room temperature and in ambient pressure. Thus prepared Cu2O/posite films were examined by X-ray diffraction, transmission electron microscopy,X-ray photoelectron spectroscopy and optical absorption spectroscopy. Compared with the pure Cu2O nanoparticles, an obvious blue shift existed in the obtained Cu2O/posite films.

3. Introduction
Nanometer-sized ultrafine particles of metals and semiconductors display many intriguing properties including optical nonlinearity, specific heat and ism properties , which are quantitatively and qualitatively different from their respective bulk materials. In the past decade, much attention has been paid to the study posite of nanometer-particles embedded in various matrixes from the viewpoint of scientific interest and their applications .
