Kind Code:
A
Abstract:
To provide a luminescent material having excellent luminous efficiency.SOLUTION: In a first embodiment, a luminescent material is provided, comprised of a compound including at least one of a naphthotriazole structure and a naphthotriazine structure. In a second embodiment, a luminescent material is provided which is identical to the luminescent material in the first embodiment except that only one naphthotriazole structure or naphthotriazine structure is included in a molecule of the compound. In a third embodiment, a luminescent material is provided which is identical to the luminescent material in the first embodiment except that a plurality of naphthotriazole structures or naphthotriazine structures is included in the molecule of the compound. In a fourth embodiment, a luminescent material is provided which is identical to the luminescent material in the third embodiment except that each of a plurality of naphthotriazole structures is bonded to another via a linking group and a naphthalene ring of the naphtotriazole structure is bonded to the linking group and one nitrogen atom constituting triazole of the naphtotriazole structure is bonded to the linking group. In a fifth embodiment, a luminescent material is provided which is identical to the luminescent material in the third embodiment except that two naphthotriazole structures are bonded each other via one linking group.SELECTED DRAWING: Figure 2
