Abstract
The present invention addresses the problem of providing particles having low photocatalytic activity and a high refractive index by forming an amorphous layer that contains Si and Ti on the surface of crystalline titanium oxide. The problem is solved by core-shell particles wherein the core particles are crystalline titanium oxide and the shell is an amorphous layer that contains Si and Ti.
