摘要：
Notch filter coatings for use in sunscreen applications are provided herein. An exemplary composition includes multiple zinc oxide particles suspended within a medium forming sunscreen composition and a combination of multiple notch filter coating materials individually applied as a distinct layer to each of the multiple zinc oxide particles to create a multi-layered structure surrounding each of the multiple zinc oxide particles within the sunscreen composition, wherein the multi-layered structure: reflects light at a user-determined wavelength range based on the wavelength range at which each of the multiple notch filter coating materials reflects light and allows wavelengths of light (i) within at least a portion of the ultraviolet spectrum and (ii) outside of the user-determined wavelength range to be absorbed by the multiple zinc oxide particles.
