(EN) SILICA GLASS MEMBER FOR WAVELENGTH CONVERSION, AND PRODUCTION METHOD THEREFOR
(FR) ÉLÉMENT EN VERRE DE SILICE POUR LA CONVERSION DE LONGUEUR D'ONDE ET PROCÉDÉ DE PRODUCTION S'Y RAPPORTANT
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 heat 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.
(FR) L'invention se rapporte à : un élément en verre de silice pour la conversion de longueur d'onde pour lequel les propriétés de tolérance à l'environnement, de résistance à la chaleur, de durabilité et de rendu des couleurs sont élevées, qui peut être produit à l'aide d'un procédé utilisant peu de chaleur et qui permet de convertir efficacement des longueurs d'onde ; et un procédé de production s'y rapportant. L'élément en verre de silice pour la conversion de longueur d'onde est formé par un substrat en verre de silice et un film de couche de surface de verre de silice formé sur la surface du substrat. Le film de couche de surface de verre de silice est obtenu par enduction de la surface du substrat en verre de silice d'une solution contenant un polysilazane, qui contient des particules de luminophore dont le diamètre moyen est de 0,1-20 μm et de fines particules de silice sphériques qui sont hydrophobes et ont une taille moyenne de 1-100 nm, séchage à l'air du substrat enduit et mise en œuvre de son chauffage dans une atmosphère de vapeur d'eau. Dans la solution contenant un polysilazane, le rapport de la quantité de particules de luminophore à la quantité totale du polysilazane et des particules de luminophore est de 10:3-7 parties en masse et la concentration de groupes NH du film de couche de surface de verre de silice est inférieure ou égale à 1000 ppm.
