OPTICAL MATERIAL, OPTICAL ELEMENT AND HYBRID OPTICAL ELEMENT

摘要

An optical material is composed of a resin material and inorganic fine particles dispersed in the resin material. Each of the inorganic fine particles has a core and a shell formed so as to cover a part of a surface of the core. The core is formed of an oxide of at least one selected from Si, Ti, Zn, Al, B, Y, Mg, Ba, Ca, Sr, Ni, Cu, In, and Sn. The shell is formed of an oxide of at least one selected from Si, Ti, Zn, Al, B, Y, Mg, Ba, Ca, Sr, Ni, Cu, In, and Sn, which is different from the oxide forming the core. The particle diameter of the oxide forming the shell is smaller than the particle diameter of the oxide forming the core. The shell is formed as crystalline fine particles.
