Title (EN) PHOSPHORESCENT SUBSTANCE AND PHOSPHORESCENT ELEMENT
(FR) SUBSTANCE PHOSPHORESCENTE ET ÉLÉMENT PHOSPHORESCENT
(JA) 蓄光体および蓄光素子
Abstract:
(EN) Disclosed is a phosphorescent substance that comprises an electron donor molecule, which comes into a stable radical cationic state, and an electron acceptor molecule, which comes into a stable radical anionic state. After light irradiation of the phosphorescent substance is stopped, luminescence is observed at 10 K. The disclosed phosphorescent substance of the invention, which may consist only of organic compounds, can emit afterglow for a long time without requiring the use of any rare-earth element.
(FR) La présente invention concerne une substance phosphorescente qui comprend une molécule donneur d’électrons, qui entre dans un état cationique radicalaire stable, et une molécule acceptrice d’électrons, qui entre dans un état anionique radicalaire stable. Après que l’exposition à un rayonnement lumineux de la substance phosphorescente est stoppée, la luminescence est observée à 10 K. La substance phosphorescente de la présente invention, qui peut être uniquement constituée de composés organiques, peut émettre une post-luminescence sur une longue durée sans nécessiter d’utilisation de quelconque élément de terres rares.
(JA) ラジカルカチオン状態が安定な電子ドナー分子とラジカルアニオン状態が安定な電子アクセプター分子を有する蓄光体であって、その蓄光体への光照射を停止した後に10Kで発光が観測される蓄光体を開示する。開示される発明によれば、希土類元素を用いずに有機化合物だけで、長時間残光を放射することができる。
