METAL COMPOUND NANOPARTICLES, COATING AND FILM USING SAME, METHOD FOR MANUFACTURING FILM, AND METHOD FOR MANUFACTURING METAL COMPOUND NANOPARTICLES

Document Type and Number:

WIPO Patent Application WO/2018/199020

Kind Code:

A1

Abstract:

According to one embodiment of the present invention, the metal compound nanoparticles are characterized in that, when metal compound particles having an average particle diameter of 50 nm or less are analyzed by spectroscopic ellipsometry and the obtained results are fitted to Lorentz model, the resonance frequency peak ωt of a vibrator is 2.8 eV or less. It is preferred that the ωt satisfies the requirement: 0.5≤ωt(eV)≤2. It is also preferred that the average particle diameter is 15 nm or less.
