SURFACE-MODIFIED ZIRCONIUM OXIDE PARTICLES, DISPERSION OF THE SURFACE-MODIFIED ZIRCONIUM OXIDE PARTICLES, TRANSPARENT COMPOSITE, OPTICAL MEMBER, COMPOSITION FOR SEALING LIGHT-EMITTING ELEMENT, AND LIGHT-EMITTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide: surface-modified zirconium oxide particles which simultaneously maintain high durability and high transparency of zirconium oxide particles and have improved optical characteristics such as a refractive index and mechanical characteristics such as hardness; a dispersion of the surface-modified zirconium oxide particles; a transparent composite, an optical member, a composition for sealing a light-emitting element, and the light-emitting element.;SOLUTION: The surface-modified zirconium oxide particles are such zirconium oxide particles that the surface of each particle is modified by an organic silicon compound. The activity of the surface of each particle is suppressed by the surface modification.;COPYRIGHT: (C)2008,JPO&INPIT
