Synthesis of High Crystalline Al-Doped ZnO Nanopowders from Al₂O₃ and ZnO by Radio-Frequency Thermal Plasma

Figure 7

Comparison of XRD patterns between the pure ZnO powders and the as-synthesized powders. The main peak corresponding to ZnO wurtzite structure shifted to the higher Bragg angle (2-theta) due to the incorporation of the Al cation into the ZnO lattice.
