| description | To provide a perovskite compound and a luminescent material composition having high stability by themselves and having excellent luminescent characteristics without aftertreatment such as curing or sealing, as well as a luminescence conversion member, a backlight unit, and a liquid crystal display device with excellent luminescent characteristics.SOLUTION: The problem is solved by using a luminescent material which includes: a core containing semiconductor nanoparticles with a perovskite crystal structure; ligands bonded to a surface of the core; and a shell covering at least a part of the core with the ligands bonded thereto, in which the ligand includes an organic acid salt and the shell includes a basic group-containing compound.SELECTED DRAWING: None
【課題】硬化や封止等の後処理に依らず、それ自体が高い安定性を有し、優れた発光特性を有するペロブスカイト化合物及び発光材料組成物、並びに、発光特性に優れる発光変換部材、バックライトユニット、及び液晶表示装置の提供。【解決手段】前記課題は、ペロブスカイト型結晶構造を有する半導体ナノ粒子を含有するコアと、前記コアの表面に結合したリガンドと、前記リガンドが結合したコアの少なくとも一部を被覆するシェルと、を含み、前記リガンドが有機酸塩を含み、前記シェルが塩基性基含有化合物を含む、発光材料によって解決される。【選択図】なし |
