摘要
A novel red light-emitting material, Ca3Al2O6:Eu3+, which is the first example found in the Ca3Al2O6 host, was prepared by calcination of a layered double hydroxide precursor at 1350 C. The precursor, [Ca2.9-xAl2Eux(OH)(9.8)](NO3)(2+x).2.5H(2)O, was prepared by coprecipitation of metal nitrates with sodium hydroxide. The material is a loose powder composed of irregular particles formed from aggregation of particles of a few nanometers, as shown in scanning electron microscope (SEM) images. It was found that the photoluminescence intensity reached the maximum when the calcination temperature was 1350 degrees C and the concentration of Eu3+ was 1.0%. The material emits bright red emission at 614 nm under a radiation of lambda = 250 nm. (C) 2008 Elsevier Inc. All rights reserved.
