Highly transparent conductive Dy2O3 doped zinc oxide (ZnO)1-x(Dy2O3)x nanocrystalline thin films with x from 0.5% to 5% have been deposited on glass substrate by pulsed laser deposition technique. The structural, electrical and optical properties of Dy2O3 doped thin films were investigated as a function of the x value. The experimental results show that the Dy concentration in Dy-doped ZnO thin films has a strong influence on the material properties especially electrical properties. The resistivity decreased to a minimum value of 5.02 Ã 10â4 Ω cm with x increasing from 0.5% to 1.0%, then significantly increased with the further increasing of x value. On the contrary, the optical direct band gap of the (ZnO)1-x(Dy2O3)x films first increased, then decreased with x increasing. The average transmission of Dy2O3 doped zinc oxide films in the visible range is above 90%.
