摘要：

A series of NaCl@LiLa(MoO4)(2):0.05Eu(3+) (denoted as NaCl@LLMO:0.05Eu(3+)) were prepared by a simple coating method. Dual emission properties induced by coating NaCl are discussed. The influence of coating NaCl on the luminescence properties of Eu3+ ions were studied. The coating of NaCl results in much more influence on the emission intensities than on the R values (R = I-2/I-1, where I-2 and I-1 are the peak area of D-5(0) -> F-7(2) and D-5(0) -> F-7(1) emissions of Eu3+ ions, respectively) of Eu3+ ions in these samples. The optimal coating content of NaCl is 48 wt% with the corresponding sample (NaCl)(0.48 wt)@ LLMO:0.05Eu(3+), whose PL intensity is as high as 1.79 times of that without coating NaCl. (NaCl)(0.48wt)@LLMO:0.05Eu(3+) is a potential red-emitting phosphor with high R values (R = 8.29) for blue light-based white LED. (C) 2017 Published by Elsevier B.V.
