Abstract
Zinc oxide compositions as well as techniques for plasmonic enhancement of zinc oxide light absorption for sunscreen applications are provided herein. One example method includes selecting one or more metal particles to be used in conjunction with one or more zinc oxide particles in a sunscreen composition, wherein said selecting is based on the plasmon resonance frequency associated with each of the metal particles; and coating at least one portion of the surface of each of the one or more zinc oxide particles with the metal particles. Another example method includes selecting one or more metal particles to be used in conjunction with one or more zinc oxide particles in a sunscreen composition, wherein said selecting is based on the plasmon resonance frequency associated with each of the metal particles; and blending the metal particles and the zinc oxide particles within a medium to create the sunscreen composition.
