摘要	The nanostructures composing of Na1-xKxErF4@NaLuF4 core@shell were synthetized with 0%-8% K+ doping mole fraction in the cores. XRD results reveal that all of the nanoparticles are the hexagonal structure. The research results show that the intensity of UCL at ~650 nm increases at first and then decreases with K+ concentration under 980 nm excitation. The intensity is enhanced 3.7 times with 4% K+ doping, compared with that of NaErF4@NaLuF4 core@shell without K+ doping. Furthermore, the slopes of relationship between UCL intensity and pumping power are from 1.91 to 1.76, for the two nanostructures undoped and doped with 4% K+, respectively. Our results suggest that the strategy of K+ doping in NaErF4@NaLuF4 nanoparticles is an efficient solution to improve the luminescence efficiency of NaErF4@NaLuF4 nanosystem. 2018, Science Press.
