Embodiment 1

[0165] Embodiment 1 (using activated alumina as a raw material, using neodymium as a stress luminescent material as a co-activator)

[0166] Strontium carbonate (SW-K manufactured by Sakai Chemical Industry Co., Ltd., 23.50 g), europium oxide (manufactured by Shin-Etsu Chemical Co., Ltd., 0.16 g), neodymium oxide (manufactured by Wako Pure Chemical Industries, Ltd., reagent, 0.06 g), Alumina (manufactured by Iwatani Chemical Industry Co., Ltd., activated alumina RG-40 (mixture of θ alumina and η alumina, α alumina content: 8 mol%), 18.04 g) was put into water (90 mL). Thereafter, using alumina balls with a diameter of 3 mm (manufactured by Nikkato Co., Ltd., SSA-999W, 190 g) as a grinding medium, dispersion, grinding, and mixing were performed using a planetary ball mill to obtain a slurry. The resulting slurry was evaporated to dryness at 130°C. The obtained solid was pulverized with a mortar to obtain a powdery raw material composition for a stress light-emitting material. ...

Embodiment 2

[0167] Example 2 (using activated alumina as a raw material and using dysprosium as a stress-luminescent material as a co-activator)

[0168] Strontium carbonate (SW-K manufactured by Sakai Chemical Industry Co., Ltd., 23.50 g), europium oxide (manufactured by Shin-Etsu Chemical Co., Ltd., 0.16 g), dysprosium acetate tetrahydrate (manufactured by Wako Pure Chemical Industries, Ltd., reagent, 0.15 g) were weighed. g) Alumina (manufactured by Iwatani Chemical Industry Co., Ltd., activated alumina, RG-40, 18.03 g) was thrown into water (90 mL). Thereafter, in the same manner as in Example 1, the target stress luminescent material was obtained in the form of powder.

Embodiment 3

[0169] Example 3 (using activated alumina as a raw material and using holmium as a stress-luminescent material as a co-activator)

[0170] Strontium carbonate (SW-K manufactured by Sakai Chemical Industry Co., Ltd., 23.50 g), europium oxide (manufactured by Shin-Etsu Chemical Co., Ltd., 0.16 g), holmium oxide (manufactured by Wako Pure Chemical Industries, Ltd., reagent, 0.07 g), Alumina (manufactured by Iwatani Chemical Industry Co., Ltd., activated alumina, RG-40, 18.03 g) was thrown into water (90 mL). Thereafter, in the same manner as in Example 1, the target stress luminescent material was obtained in the form of powder.

Abstract

The purpose of the present invention is to provide: a mechanoluminescent material which has excellent mechanoluminescent properties and can achieve sufficient luminous intensity for practical use applications; a raw material composition for providing the mechanoluminescent material; and a method for producing a mechanoluminescent material. The mechanoluminescent material according to the present invention is mainly composed of strontium aluminate and contains a Eu ion and at least one ion selected from the group consisting of a Nd ion, a Dy ion and a Ho ion, wherein the amount of the Eu ion contained in the mechanoluminescent material is 0.0001 to 0.1 mole per 1 mole of the above-mentioned strontium aluminate and the amount of the at least one ion selected from the group consisting of the Nd ion, the Dy ion and the Ho ion contained in the mechanoluminescent material is 0.0001 to 0.01 mole in terms of the total amount of the three kinds of ions, i.e., the Nd ion, the Dy ion and the Ho ion, per 1 mole of the above-mentioned strontium aluminate. Also provided are: a raw material composition for a mechanoluminescent material, which can be used for the synthesis of the above-mentioned mechanoluminescent material; and applied products such as a mechanoluminescent coating composition containing the mechanoluminescent material, a resin composition containing the mechanoluminescent material and a mechanoluminescent material formed from the resin composition.

Description

technical field [0001] The present invention relates to a stress luminescent material and its application, a raw material composition for a stress luminescent material, and a manufacturing method of a stress luminescent material. Background technique [0002] There are known light-emitting materials in which a substance emits visible light at around room temperature in response to external stimuli. Among them, a material that emits light under the mechanical stimulus of an external force (compression, displacement, friction, impact, etc.) is called a stress luminescent material. [0003] As a stress luminescent material, a stress luminescent material using an aluminate as a matrix has been reported (for example, Patent Documents 1 and 2). However, in the existing stress luminescent materials, no practical luminous brightness has been obtained, and a stress luminescent material capable of achieving higher luminous intensity is required. [0004] prior art literature [000...
