英文摘要: The influence of lithium doping on the crystallization behavior, morphology, and enhancement in photoluminescence intensity of SnO2:Eu was investigated. In order to attain high homogeneous and pure samples, the Pechini type sol-gel method was adopted for the synthesis at low temperature (500 degrees C). The structure and morphology were characterized by using X-ray diffraction (XRD) and transmission electron microscope (TEM). The results indicate that the Li+ doping could accelerate the crystallization of SnO2 and the particle size of the phosphors is below 100nm. In particularly, the incorporation of Li+ ions into SnO2 lattice could induce a remarkable increase of photoluminescence intensity. (c) 2005 Elsevier B.V. All rights reserved.
