In this paper, using calcium chloride and sodium molybdate as raw material, polyethylene glycol (PEG2000) as surfactant, the nanocomposites of CaMoO₄: Eu³⁺ were prepared by a direct feeding microwave synthesis method. The as-prepared 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 as-prepared samples have strong luminescence properties; it had purity red emission at 615 nm. The effects of different Eu³⁺ ions doping amount and surface active agent on the photoluminescence properties were studied. The results showed that when the molar ratio of Eu³⁺ was 0.10, PEG2000 as surfactant, the luminescence intensity of as-prepared sample was maximum.
