Dielectric Properties of Aluminium and Silver Doped Zinc Oxide Nano Powder Prepared by Solution Combustion Synthesis

Abstract

Aluminium and Silver doped Zinc Oxide nano powder were synthesized by Solution Combustion method using Sucrose (C12H22O11) as fuel at 600o C. X-Ray diffraction pattern analysis confirms synthesized nano powders crystalized in single phase wurtzite structure matched with JCPDS-36-1451. Addition of dopant controls the crystallite size of the synthesized nano powder. The study of dielectric permittivity, dielectric loss, AC conductivity and impedance were investigated in the frequency range of 100Hz to 5MHz at room temperature. It is evident from the analysis that dielectric properties of the samples depends on the nature of the dopant.
