PROBLEM TO BE SOLVED: To obtain the subject material enabling not only to control the diameters of particles in a production process but also to disperse the particles in a high concentration and useful as an optical material, a sensor material, etc., by reacting surface-modified semiconductor ultrafine particles having functional groups on the surfaces with a resin. SOLUTION: This resin material is obtained by reacting a compound (a thiol compound having an amino group) having two or more functional groups (amino group, etc.), or a compound having two or more functional groups and a compound having one kind of functional group (thiophenol, etc.), with semiconductor ultrafine particles (silicon ultrafine particles, oxide semiconductor ultrafine particles or 12-16 group ultrafine particles having particle diameters of 1-100 nm, etc.), and subsequently reacting the produced surface-modified semiconductor ultrafine particles with a resin having functional groups (e.g. an amino styrenic resin produced by aminating polystyrene). |
