The invention discloses a long persistent luminescence emitter which has an electron-donating molecule that is stable in the radical cation state and an electron-accepting molecule that is stable in the radical anion state and from which luminescence is observed at 10 K after photo-irradiation of the long persistent luminescence emitter stops. According to the disclosed invention, persistent luminescence can be exhibited for a long time with only organic compounds without the use of any rare-earth elements.
本发明公开了一种长持续发光发射体,该发射体具有在自由基阳离子状态下稳定的供电子分子和在自由基阴离子状态下稳定的受电子分子,在停止对长持续发光发射体进行光照射后,可在 10 K 温度下观察到该发射体发光。根据本发明,只需使用有机化合物,而无需使用任何稀土元素,就能长时间发出持久性发光。
