Abstract: The present invention provides a method for easily and simply producing a zinc oxide phosphor that has a high level of safety and a high emission intensity and is useful for, for example, cosmetic applications. The present invention also provides a zinc oxide phosphor having such excellent physical properties and a cosmetic product containing the same. Provided is a method for producing a zinc oxide phosphor, including: a raw material mixing step of mixing an oxygen-containing zinc compound and a sulfur-containing compound; and a firing step of firing the raw material mixture obtained in the raw material mixing step, the firing step including firing in a reducing atmosphere followed by firing in an oxygen-containing atmosphere.

Abstract: The present invention aims to provide a mechanoluminescent material which is excellent in mechanoluminescent properties and can achieve a mechanoluminescence intensity sufficiently suited to practical use, a raw material composition for producing the mechanoluminescent material, and a method for producing a mechanoluminescent material. The mechanoluminescent material of the present invention includes strontium aluminate as a base material, a Eu ion, and at least one ion selected from the group consisting of Nd, Dy, and Ho. An amount of the Eu ion contained in the mechanoluminescent material is 0.0001 to 0.1 mol per mole of the strontium aluminate. An amount of the at least one ion selected from the group consisting of Nd, Dy, and Ho contained in the mechanoluminescent material is, as the sum of amounts of the three ions Nd, Dy, and Ho, 0.0001 to 0.01 mol per mole of the strontium aluminate. The present invention also provides a raw material composition for a mechanoluminescent material used for synthesizing the mechanoluminescent material, a mechanoluminescent coating composition and a resin composition each containing the mechanoluminescent material, and applied articles such as mechanoluminescent articles formed from the resin composition.
