Abstract:As raw materials of Cd ( NO3 ) 2 and Na2 MoO4 , CdMoO4 microspheres were synthesized with NH4 Cl as mineralizer via hydrothermal method at pH =8 and 200℃for 12 h.The effects of the additive amount of mineralizer were investigated on morphologies and luminescence properties of CdMoO 4 by means of X-ray dif-fraction (XRD), the field emission scanning electron microscopy (SEM) and fluorescence spectra (PL).The results showed that the obtained products were CdMoO 4 microspheres with pure tetragonal phase as the mineral-izer of NH4 Cl;while the additive amounts of NH 4 Cl were increased , the crystallinity degree of the crystals was heightened , the diameter and dispersion degree of the crystals were increased and the fluorescence intensities of CdMoO4 crystals doped by Eu3+were enhanced gradually.When the ratio of n(NH4Cl)∶n(Na2MoO4) was e-qual to 4∶1, the monodisperse CdMoO 4 microspheres was obtained with diameter of ~5 μm.The diameters of the CdMoO4 microspheres were diverse with different additive amounts of mineralizer , so the size of the CdMoO 4 microspheres can be controlled by adjusting the amount of mineralizer .
