The synthesis and photoluminescent properties of one-dimensional ZnMoO4:Eu3+ nanocrystals

ZnMoO4:Eu3+ nanocrystals were synthesized by a mild and simple hydrothermal method. The results indicate that the pH value of the precursor solution plays a crucial role in controlling the morphology, size and structures. The leaflike, nanorods and nanowires were obtained by modulating the pH value of the precursor solution. The crystalline structure of ZnMoO4:Eu3+ nanocrystals are affected by the precursor solution. The excitation and emission spectra were studied. The results indicate that relative intensity of f-f transitions to charge transfer (CT) absorption and D-5(0)-F-7(2) to D-5(0)-F-7(1) transitions greatly change in different samples.
