Synthesis and Characterization of N-doped Pink ZnO Nanocrystalline by Combustion Method

N-doped ZnO(NZO)nanocrystallines were synthesized by combustion method using urea as main fuel,surfactant as assistant fuel and zinc nitrate as oxidant.The effects of calcination temperature and molar ratio of urea to zinc nitrate on the properties of the synthesized samples were investigated. The variation of adiabatic flame temperature(T_(ad))with the various fuel-to-oxidizer molar ratios value was calculated theoretically according to the thermodynamic principle.XRD,FTIR,SEM and XPS were used to characterize the properties of the samples respectively.The experimental results show that perfect pink powders with standard cubic ZnO crystal phase are obtained at 800~C when molar ratio of the urea to zinc nitrate is 4.920 and the concentration of the zinc nitrate is 60g/L.The average primary granularity of the as-synthsized sample is about 30nm estimated according to Scherrer Equation.XPS analysis indicates that the nitragen concentrantion in the N-doped ZnO sample is 1.02%.And the obtained N-doped ZnO film has perfect ultraviolet prevention ability.
