Luminescence from the 5D1,2,3 excited states of Eu3+ in Y4Al2O9 crystal
Source abstract
Abstract
Abstract The site-selective emission originating from 5 D 1,2,3 energy levels of Eu 3+ in Y 4 Al 2 O 9 (YAM) monoclinic bulk crystal is investigated. Energy and Stark splitting of excited states of europium in YAM are determined based on the low temperature absorption and emission spectra. Luminescence decays of three different sites of Eu 3+ ions are measured as a function of temperature and europium concentration. The cross-relaxation among the Eu 3+ ions are observed and discussed. Non-resonant mechanisms responsible for the temperature quenching of 5 D 1 emission are proposed.
