J Nanosci Nanotechnol. 2011 Nov;11(11):9808-12. Spectroscopic study of Eu3+ doped LaF, nanoparticles prepared with different PH values. Tian Y1, Zheng H, Cui M, Fu Z, Gao D, Gao W. 1College of Physics and Information Technology, Shaanxi Normal University, Xi'an 710062, P. R. China. Abstract Europium doped lanthanide fluoride (LaF3) nanoparticles were prepared through a hydrothermal method with different PH values of precursor complex solution. The influence of PH value on the luminescence properties is investigated. It was found that the local symmetry of doped ions reduced with the increase of PH value, leading to the increase of the inversion symmetry ratio. The fluorescence quenching was observed for small nanoparticles, which was attributed to the large amount of OH groups absorbed to the surface of the nanoparticles. 哪里都找不到这篇论文，有哪位学霸能帮忙找一下呀~~非常感谢啦！ |
