SYNTHESIS AND CHARACTERIZATION OF ZNO MICROCRYSTAL TUBES

Zinc oxide microcrystal tubes were prepared by using H(2)0(2)-activated Zn powder and active carbón as raw materials. The prepared samples were characterized by powder X-ray diffraction, scanning electrón microscopy and fluorescence spectrophotometer. The results indícate that ZnO microcrystal has t...
