Nitride-based nanoparticles for use in sunscreen applications

Abstract

Nitride-based nanoparticles for use in sunscreen applications provided herein. A method includes selecting one or more nitride-based nanoparticles to serve as a core material in a sunscreen composition, wherein said selecting is based on a desired absorption spectrum of the sunscreen composition, and adjusting an amount of at least one element present within the nitride-based nanoparticles to achieve one or more user-defined optical characteristics with respect to the core material in the sunscreen composition. A composition includes one or more nitride-based nanoparticles constituting a core material in a sunscreen composition, wherein said nitride-based nanoparticles are selected based on a desired absorption spectrum of the sunscreen composition, and wherein an amount of at least one element present within the nitride-based nanoparticles is adjustable to achieve one or more user-defined optical characteristics.
