摘要：

The codoped nanoparticles by Aluminium and Nickel were prepared by sol???gel method and theirs different physical properties were studied. The obtained nanoparticles were undergoes a heat treatment in air at different temperatures ranging from 500 ??C to 1000 ??C in 2 hours. The structural results revealed that the structure is wurtzite with an average crystallite around 30nm, and the appearance of NiO second phase. The optical spectroscopy (UV-Vis) shows a red shift in band gap values with increasing of heat treatment temperature. Photoluminescence (PL) results indicate the effects of oxygen vacancies on emission spectra and confirms the shift of band gap energies. Magnetic measurements at 300K showed a superparamagnetic behaviors.
