    Abstract: A method for deposition glass soot for making an optical fiber preform. A fuel and a glass precursor are flowed to a burner flame forming glass soot which is deposited onto a glass target. By first depositing an insulating layer of glass soot with a low velocity burner flame, the amount of water which may be adsorbed into the surface of the glass target can be reduced. Thereafter, the flame velocity may be increased to increase the deposition rate of the glass soot without significantly increasing the concentration of water incorporated into the glass target.

    Abstract: It is an object of the present invention to provide a light emitting device of the next generation optical device having a broad emission property that a width at half maximum of an emission spectrum is large in a wavelength range of visible light and capable of recognizing white light emitting by photoluminescence (PL). In a baking process for baking a pressure molding formed by pressure molding of silica fine particles such as fumed silica, a baking temperature is made as not more than 1000° C., hydroxyl groups of the silica fine particles are sufficiently subjected to dehydration condensation reaction so that the particles becomes transparent, a structural defect generated in the process is held without being relaxed, and thus a silica glass is generated. The silica glass is employed as a fluorescent substance.
