Structural and Optical Properties of Li Doped Zirconia Nanoparticles
A. Abirami, M. Prema Rani
Li-stabilized cubic zirconia nanostructures (Zr1-xLixO2, x = 0.15, x = 0.25 and x = 0.35) have been prepared using a chemical precipitation method. The average size of the prepared crystallite was 17 nm. The electronic distributions in the unit cell were analyzed using the MEM method for the prepared cubic zirconia nanostructure. The bonding features were analyzed and it is found to behave like an ionic material. The energy band gap was determined via UV analysis and is found to be 4.13 eV for pure ZrO2.
