| Abstract | In this paper, using calcium chloride and sodium molybdate as raw material, polyethylene glycol (PEG2000) as surfactant, the nanocomposites of CaMoO4: Eu were prepared by a direct feeding microwave synthesis method. The asprepared sample was characterized by X-ray diffraction (XRD), scanning electron micrograph (SEM) and photoluminescence spectrum (PL). The XRD Pattern showed that the samples are scheelite structure of CaMoO4. The SEM image showed that the majority of as-prepared sample is a relatively flake structure, and some fine particles attached to it. PL spectra showed that asprepared samples have strong luminescence properties; it had purity red emission at 615 nm. The effects of different Eu ions doping amount and surface active agent on the photoluminescence properties were studied. The results showed that when the molar ratio of Eu was 0.10, PEG2000 as surfactant, the luminescence intensity of as-prepared sample was maximum. |
