英文摘要: Yb3+/Ho3+/Li. tridoped Lu6O5F8 as a novel phosphor was prepared by a coprecipitation method. It is found that Li+ doping could enhance the emission intensity of Yb3+/Ho3+ codoped Lu6O5F8 both under the excitation at 980 nm and low-voltage electron beam. Under 980 nm laser excitation, the intensity of red emission is slightly stronger than that of green emission, generating an overall yellow output in Lu6O5F8:20%Yb3+,1%Ho3+,x%Li (0 <= x <= 8) nanoparticles, and the reason for this phenomenon is discussed in detail. Meanwhile, under low-voltage electron beam excitation, spectral results demonstrated that the intensity of red emission is much stronger than that of green emission, yielding a red color output. Therefore, Lu6O5F8:20%Yb3+,1%Ho3+,x%Li+ (0 <= x <= 8) nanoparticles have potential applications in luminescent display panels and field emission displays. (C) 2016 Elsevier Ltd. All rights reserved.
