Abstract
his report presents the results of the fabrication of luminescent terbium orthophosphate monohydrate (TbPO4
H2O) nanomaterials prepared by the microwave synthesis method and their characterization. The effects of synthesis conditions such as microwave irradiated powers, pH values and reaction temperature on properties of nanomaterials are also investigated to obtain controllable size, morphology and strong luminescence. The structure, morphology and optical properties of the nanomaterials have been characterized by x-ray diffraction, field-emission electron scanning microscopy and fluorescence spectroscopy, respectively. The results showed that TbPO4H2Onanowires/nanorods have been successfully synthesized by using microwave heating of an aqueous solution of terbium nitrate and NH4H2PO4 with pH values ranging from 2 to 10. The length and width of these nanowires/nanorods are 150–350 nm and 5–10 nm, respectively
