PROBLEM TO BE SOLVED: To provide a method for forming a thin film of vanadium oxide phosphor represented by a composition formula AVO<SB>3</SB>having excellent crystallinity, in a low temperature range from a room temperature to 400°C and forming it directly on an organic substrate which is conventionally difficult, without a binder. SOLUTION: A vanadium oxide phosphor thin film represented by the composition formula AVO<SB>3</SB>is obtained by holding, at 25-450°C, a thin film formed on a substrate and containing A (A is one or more atoms selected out of K, Rb and Cs) and V substantially at an atomic ratio of 1:1 and then irradiating the thin film with ultraviolet laser beams with a wavelength of 400 nm or less to crystallize a vanadium oxide.
