Title SILVER NANOPARTICLE COMPOSITE, SILVER NANOPARTICLE COMPOSITE SUSPENSION USING THIS, COMPOSITION FOR γ-RAY-SENSITIVE SENSOR FORMATION AND γ-RAY SENSITIVE SENSOR, AND METHOD FOR MANUFACTURING SILVER NANOPARTICLE COMPOSITE
Abstract

Provided is a silver nanoparticle composite which is obtained by adsorption of a plurality of triangular flat plate-shaped silver nanoparticles onto the planar face of flat plate-shaped metal oxide particles. The shape of the main planar face of the plurality of triangular flat plate-shaped silver nanoparticles is triangular or substantially triangular, the initial average longest diameter of the main planar face is 20 to 120 nm, and the initial average thickness is at least 5 nm but less than 20 nm. The flat plate-shaped metal oxide particles comprise a metal oxide of positive ? potential at pH 5 to 7 and, as the planar face, have a planar face having an average diameter of 16.7 to 500 times the initial average longest diameter of the triangular flat plate-shaped silver nanoparticles. In the silver nanoparticle composite, at least 75% of the total number of silver nanoparticles that are adsorbed onto this planar face are silver nanoparticles of triangular flat plate shape and maintain a shape that satisfies the conditions of the main planar face shape thereof being triangular or substantially triangular, the longest diameter of this main planar face being 20 to 120 nm, and the thickness thereof being at least 5 nm but less than 20 nm.
