Abstract

It is one of the objects of the present disclosure to provide hexagonal prism-shaped zinc oxide particles having improved ultraviolet shielding ratio at the wavelength of 400 nm or less without impairing the direct transition properties of electronic excitation thereof and having remarkably improved ultraviolet shielding ratio for UV-B radiation and UV-A radiation; and a zinc oxide particle containing a solid solution of a Ti element and/or a Fe element and a Zn element in at least a portion thereof, and having a hexagonal prism shape.
