摘要： [Problem] To provide a luminescent sheet having an excellent light emission performance and capable of preventing forgery.[Solution] A luminescent sheet 1 has a first base material layer, at least one of recesses 3 and projections 4 having edges and formed on a first base material layer 2, and stress-luminescent parts each arranged at a location contacting with the edge. At least a part of the edges has a stress concentrated part where stress concentrates when stress is added to the first base material layer in a predetermined direction. The stress-luminescent part emits light having a predetermined wavelength with a light-emitting intensity depending on external load stress added to the stress concentrated part.

摘要： There is provided a luminescent medium which requires difficult analysis of light emitted from a luminescent material of the medium. A luminescent medium 10 includes a substrate 11, and a luminescent material 12 comprising a first luminescent material 12A which, when irradiated with visible light, infrared light or ultraviolet light, emits first infrared light “a”, and a second luminescent material 12B which, when irradiated with visible light, infrared light or ultraviolet light, emits second infrared light “b”. The first luminescent material 12A is formed in a first planar area 11A, and the second luminescent material 12B is formed in a second planar area 11B. The first planar area 11A and the second planar area 11B overlap each other, forming an overlapping planar area 11C in which the luminescent materials 12A and 12B each have a concentration gradation.
