The Effect of MgO Dopant and Laser Treatment on ZnO Ceramic

Abstract

ZnO ceramic samples as pellets have been prepared and doped with (1, 2.5, 5, 10 wt%) of MgO powder, sintering at 1300˚C, these samples have been treated with laser at 400 J/cm 2 . X-ray diffraction spectra of the samples show some changes in the X-ray parameters, where d-spacing and the intensities of the peaks are changed. FWMH of all the samples was altered due to MgO dopant and the laser influence microstructure was affected by the laser treatment, also, the texture coefficient is affected.

Luminescence and electrochemical properties of rare earth (Gd, Nd) doped V2O5 nanostructures synthesized by a non-aqueous sol–gel route

“…This shiing in XRD lines of the doped V 2 O 5 suggests that Gd 3+ and Nd 3+ have been successfully doped into the pure V 2 O 5 host structure at the V 5+ site and it is ascribed to the decrease in the values of 'd' spacing. 27 The estimated lattice parameters are depicted in Table 1. When compared to the 'd' spacing of pristine V 2 O 5 , both the doped samples possess smaller 'd' spacing values for all the diffraction angles.…”
