| 摘要 |
A stress-luminescent material emits luminescence when external mechanical energy is applied thereto. The fine particles of the material have an anisotropic aspect ratio, preferably, from 2 to 1000, more preferably, from 5 to 100. Raw materials are mixed together in an aqueous solvent, and aqueous ammonia is added thereto to change the pH value, thereby controlling the aspect ratio of the stress-luminescent material particles. Also provided are compositions containing the stress-luminescent material, such as a coating material, an ink, and an adhesive.
