Title: (EN) QUARTZ GLASS MEMBER FOR WAVELENGTH CONVERSION AND METHOD OF MANUFACTURING THE SAME
Abstract: front page image
(EN)

Provided are a quartz glass member for wavelength conversion that is high in environmental resistance, heat resistance, durability, and color rendering property, can be manufactured by a low temperature process, and can efficiently convert a wavelength, and a method of manufacturing the same.

The quartz glass member for wavelength conversion includes: a quartz glass base material; and a quartz glass surface layer film formed on a surface of the quartz glass base material, in which: the quartz glass surface layer film is obtained by applying, onto the surface of the quartz glass base material, a polysilazane-containing solution containing fluorescent material particles having an average particle diameter of from 0.1 μm to 20 μm and silica fine particles each having a spherical shape and hydrophobicity and having an average particle diameter of from 1 nm to 100 nm, followed by drying in air and then beat treatment in a water vapor atmosphere: the polysilazane-containing solution has a ratio between a total amount of polysilazane and the fluorescent material particles and the fluorescent material particles of from 10:3 to 10:7 in terms of mass; and the quartz glass surface layer film has an NH group concentration of 1,000 ppm or less.
