摘要:
In one embodiment of the present invention, on the surface of a material to be measured for stress analysis which has a stress-induced luminescent material layer formed thereon, a distortion energy is disclosed which is transmitted from a base material of a stress-induced luminescent material to the stress-induced luminescent material with high efficiency. The material to be measured for stress analysis has, on the surface thereof, a coating film layer, which emits light upon exposure to a change in distortion energy. The coating film layer is formed of a synthetic resin layer containing stress-induced luminescent particles, and the modulus of elasticity of a base material is not less than 1.0 GPa. The thickness of the coating film layer is preferably 1 μm to 500 μm.

One embodiment of the present invention provides (i) a luminant having a unique crystal structure so as to exhibit high luminosity and (ii) a manufacturing method thereof. Further, the present invention discloses (I) a luminant which exhibits ultraviolet luminescence and (II) a manufacturing method thereof. The inventors developed a stress-stimulated luminescent material which exhibits high luminosity by using a compound having a structure obtained by inserting alkali metal ions and alkali earth metal ions into a base material structure constituted of polyhedral-structure molecules and partially substituting the alkali metal ions and alkali earth metal ions by rare earth metal ions, transition metal ions, group-III metal ions, or group-IV metal ions. Further, the inventors developed a stress-stimulated luminescent material which exhibits high-luminosity stress-stimulated ultraviolet luminescence by adding specific metal ions such as Ce as a luminescent center to the aforementioned stress-stimulated luminescent material.
