    摘要: 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 alkaline 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.
