Characterization of Nano-Rod ZnWO4 Prepared by Surfactant-Assisting Solvothermal Reaction

Abstract:

Article Preview

Nano-rod ZnWO4 was solvothermally prepared by the reaction of Zn(CH3COO)2.2H2O with Na2(WO4).2H2O in water at 150-200 oC using the pH of 5.0, 7.0, 9.0 and 12.0 for 24, 48 and 72 h. N-cetyl pyridinium chloride was used as a surfactant. By using XRD, SAED, EDX and TEM, nano-rod ZnWO4 containing Zn, W and O was detected. The pH values can play a role in the length of the nano-rods and their crystallinities. FTIR revealed the presence of Zn-O-W, W-O and Zn-O stretching vibrations of the products. Their photoluminescent (PL) spectra are similar and the wavelengths at the highest intensities were detected over the range of 445-450 nm.
