rare-earth nanocompositeswere prepared by a facile co-precipitation method with the aid of ultrasonic technique.The cross sections of the nanocomposite were observed by scanning electron microscopy (SEM)

and the luminescent properties of the nanocompositeswere studied by fluorescence spectroscopy.The SEM results showed that the (Y
