Abstract
A method for preparation of inorganic fine particle-organic crystal hybrid fine particle comprising; pouring an organic material having π-conjugated bond as a water soluble solution into aqueous dispersion in which inorganic fine particles of 50 nm or less selected from the compound group consisting of metal fine particles, semi-conductor fine particles, fine particles of inorganic fluorescent material and fine particle of inorganic luminescent material, are dispersed, co-precipitating said inorganic fine particle which forms a core into said organic material which forms a shell in said dispersion and forming shell of fine crystal of said organic material on the surface of the core of said inorganic fine particles of 50 nm or less by controlling the size of said inorganic fine particle and by controlling the adding amount of said organic material.
