Influence of Co doping on ZnO film
|
Abstract:
The Co2+ ions doped ZnO diluted magnetic semiconductor films, Zn1-xCoxO, were prepared on glass substrate using PVA method. The structure of Zn1-xCoxO thin films with different x value and its photoluminescence properties were investigated. The vibrating sample magnetometer (VSM) measures the ferromagnetic properties of Zn0.88Co0.12O thin films at room temperature. We analyzed the influence of doping content on its luminescence performance, and discovered that with the doping content increasing, the blue luminescence peak shows a red shift.
