Study of dielectric property on ZrO₂ and Al doped ZrO₂ nanoparticles

A solution combustion process was used to synthesize ZrO₂ and Al doped ZrO₂ nanoparticles by using Zirconium nitrate and aluminium nitrate as the oxidizer and glycine as fuel. The prepared samples were characterized by several techniques such as X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), UV-visible spectroscopy (UV-vis). The dielectric values of the pelletized samples were examined at room temperature as the function of frequency. XRD shows the structure of the prepared and doped samples. The SEM shows the surface morphology of the pure and doped ZrO₂ nanoparticles. The dielectric property enhances with increase of Al concentration, which is useful in dielectric gates. (author)
