摘要
The influence of polyvinylpyrrolidone(PVP)and monoethanolamine(MEA)as surfactants on photoluminescence(PL)of Eu-doped ZnO(ZnO:Eu)has been studied.X-ray diffraction(XRD)results show that there are more Eu3+ions to replace Zn^2+ ions into ZnO lattice for ZnO:Eu in the presence of surfactant MEA.From the spectral analysis for ZnO:Eu with different surfactants by Gaussian deconvolution,it can be seen that the use of MEA as a surfactant affects the energy transfer from ZnO host to Eu^3+ions and leads to three new emission peaks,including UV emission(389 nm),violet emission(411 nm)and green emission(506 nm).
