日本九州工业技术研究所功能陶瓷研究室研制成受到应力时发生可逆性反应的无机系力致发光材料。制成这样的无机系材料尚属首次。材料的表面形成薄膜 ,受到外力 (压缩、撞击、摩擦、弯曲、拉伸 )时就发出强度与外力成比例的光 ,预期可应用于应力分布等的测定。力致发光现象分为 Japan Kyushu Institute of Industrial Technology Ceramics functional research into the stress-induced reversible reaction of inorganic electroluminescence materials. For the first time made of such inorganic materials. The surface of the material forms a thin film. When subjected to an external force (compression, impact, friction, bending, stretching), light is emitted in proportion to the external force, which is expected to be applied to the measurement of stress distribution and the like. Power induced luminous phenomenon is divided into
