摘要：

Cr-doped ZnO thin films are deposited by sol-gel dip coating. The effect of Cr on the structural, magnetic and optical parameters of zinc oxide films is studied. X-ray diffraction patterns of Cr-doped ZnO thin films are found to have a hexagonal wurtzite structure of ZnO. The bandgap energy of the Cr-doped ZnO thin films is calculated by the Tauq method. Crystallite size is evaluated by the Scherrer and Williamson-Hall relation. Both show that crystallite size enhances with an enhancement in Cr doping. The bandgap energy of the Cr-doped ZnO thin films is decreased by increasing the Cr dopant. The films are found to be ferromagnetic with a decrease in magnetic properties with an increase in Cr content.
