Document Type and Number:
WIPO Patent Application WO/2020/129916
Kind Code:
A1
Abstract:
A UV excitation light source 10A comprises a phosphor 14. The phosphor 14 contains ScxY1–xPO4 crystals (wherein 0 < x < 1), and, upon receiving UV light of a first wavelength, generates UV light of a second wavelength that is longer than the first wavelength. A method for producing the phosphor 14 includes: a first step for producing a mixture that includes an oxide of Y, an oxide of Sc, phosphoric acid, and a liquid; a second step for vaporizing the liquid; and a third step for baking the mixture.
