CaMoO4 nanostructures with different morphologies, such as ellipsoid-like, spindle-like, and sphere-like, were successfully synthesized in a simple cationic surfactant-CTAB-microemulsion system at room temperature. The molar ratio (w) of H2O to CTAB and the concentration of reactants played important roles in the morphological control of CaMoO4 nanostructures. A possible mechanism was proposed for the selective formation of the different morphologies. The CaMoO4 nanostructures exhibited excellent photoluminescence properties with the same new green emission peaks at 495 nm. (C) 2009 Elsevier B.V. All rights reserved.
