Amorphous Cerium−Titanium Solid Solution Phosphate as a Novel Family of Band Gap Tunable Sunscreen Materials

Abstract

A series of amorphous phosphates of Ce1-xTixP2O7 has been developed as a band gap tunable inorganic material. The optical absorption edge can be tuned through the desired range in the ultraviolet region by simple composition adjustments. This amorphous material consists of harmless elements and is a promising safety sunscreen agent.
