Abstract

PROBLEM TO BE SOLVED: To prepare sol-gel glass containing ultrafine silicon particles dispersed uniformly or nearly uniformly in the sol-gel matrix, and to provide a method for manufacturing the sol-gel glass. SOLUTION: A primary starting solution is prepared by mixing tetraethoxysilane (Si(OC2H5)4) in such a way that the molar ratio of Si(OC2H5)4: C2H5OH:H2O:HCl:DMF is adjusted to 1:4:10:0.3:1, ultrafine silicon particles are dispersed in ethanol by 8.3 wt.% of the amount of the tetraethoxysilane to prepare a suspension and 5 ml of the ethanol suspension is added to the primary starting solution to prepare a final starting solution. This sol-gel solution is applied to a quartz substrate of 10 mm×40 mm by a dipping method and dried at room temperature in the air for about 100 hr to manufacture the objective sol-gel dip glass. The PL spectrum of the resulting thin film glass measured confirms that ultrafine silicon particles are incorporated in the glass matrix.
