Zno Nanoparticles Research Papers
• Cu-doped ZnO (Zn 1-x Cu x O) nano-ceramics were prepared by ball-milling of the CuO and ZnO powders • Up to 3 at% of Cu could be doped in ZnO via ball milling, beyond which Cu precipitates as CuO during calcination • The ac conductivity values decrease by Cu doping in ZnO, making it a better dielectric material.
