Aitasalo, P. Deren, J. Hölsä, H. Jungner, J.C. Krupa, M. Lastusaari, J. Legendziewicz, J. Niittykoski, and W. Strek. Persistent luminescence phenomena in materials doped with rare earth ions. ''J. Solid State Chem.'', 171 :114, 2003.〕 However, the phenomenon of persistent luminescence must not be mistaken with fluorescence and phosphorescence (see for definitions 〔(IUPAC Gold Book - fluorescence )〕 and 〔(IUPAC Gold Book - phosphorescence )〕). Indeed, in fluorescence, the lifetime of the excited state is in the order of a few nanoseconds and in phosphorescence, even if the lifetime of the emission can reach several seconds, the reason of the long emission is due to the deexcitation between two electronic states of different spin multiplicity. For persistent luminescence, it has been known for a long time that the phenomenon involved energy traps (such as electron or hole trap) in a material〔H.W. Leverenz. Luminescent solids (phosphors). ''Science'', 109 :183–189, 1949.〕 which are filled during the excitation. After the end of the excitation, the stored energy is gradually released to emitter centers which emit light usually by a fluorescence-like mechanism. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Persistent luminescence」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
