PROBLEM TO BE SOLVED: To simply obtain an organic solid illuminant which comprises a solid aromatic compound bearing an imino group, manifests luminous phenomenon even in the solid state and is stable and excellent in fluorescence properties. SOLUTION: This solid illuminant comprises a solid aromatic compound bearing an imino group of the formula: -C=NR (R is H, a functional group or organic group, preferably an aliphatic, aromatic, carbocyclic aromatic, heterocyclic aromatic, hydroxyl), typically N-benzylidene)methylamine, N-(naphthylidene)aniline, N-phenyl-troporone-1-imine, N-(α-methylbenzylidene) methylamine, N-phenyl-troporon-1-imine or the like. There compounds are obtained by condensation reaction between an aromatic aldehyde or an aromatic ketone and an amine.
