摘要：
Cu-doped zinc oxide thin films are dip coated on glass substrates. Zinc acetate and copper acetate are used as metal precursors to synthesize sol. XRD scanning discloses that all films have the hexagonal wurtzite structure of ZnO. All films are a-axis oriented with preferred orientation along (101). Crystallite size of thin films increased with the increase in the Cu doping percentage from 2 to 10 wt%. TGA scrutiny predicted that weight loss takes place till 530 °C. Increase in Cu doping leads to insignificant decrease in the optical band gap of the thin films. All films show ferromagnetic properties which are due to hybridization of p–d orbitals.
