Eu3+-doped CdMoO4 red phosphor synthesized through an aqueous solution route at room temperature

Eu3+-doped CdMoO4 red phosphor was prepared by a simple aqueous solution process at room temperature. X-ray diffraction (XRD), scanning electron microscopy and transmission electron microscopy were used to characterize the phosphor. Emission and excitation spectra show that the phosphor exhibits a dominant red emission at 617 nm with excitation wavelength of 300 nm at room temperature. The red emission is visible to naked eye, indicating that CdMoO4 is a new promising host material for the rare-earth elements. This result may bring opportunity for the generation of rare-earth element doped complex metal oxides with low cost and gram scale production.
