As a kind of metastable aggregation between the iron ions and iron hydroxide precipitates, Fe clusters only can be isolated in the narrow synthesis condition. Here, two Fe clusters with...
Size and shape uniformity of nanomaterials are extremely important for their applications in batteries, supercapacitors, catalysis, etc. In the crystallization process, finding proper synthesis condition is necessary to control over...
Preparation of MgO and Mg0.95Zn0.05O nanomaterials using self-propagating combustion method are done to investigate the effect of doping on the band gap energy. The synthesis condition has been optimized to obtain pure MgO and Mg0.95Zn0.05O materials which confirmed by XRD. FESEM results shows agglomeration of crystallite with average crystallite size of samples between 30 nm to 125 nm. The band gap obtained from the measurement of UV-Vis NIR spectrophotometer for MgO nanostructure is 6.36 eV which is lower than bulk MgO of 7.8 eV. The presence of Zn in Mg0.95Zn0.05O sample causes the narrowing of band gap to 5.33 eV.
