Abstract

Nanostructured ZrO2 and ZrO2: Cu were prepared employing CSP method. XRD anaylsis assures that ZrO2 offer the formation of crystalline phase with (200) plane by increasing Cu-doping. Crystallite size (D) increases from ( 15.990 -19.780) nm as Copper content increase, whilst strain (ε) decreased from 2.160 to 1.750 , whilst dislocation density (δ) reduction from 3.91 to 2.55. AFM technique was employed to know the film topography . The AFM have revealed that particle size observed was in the zone of (82.310 - 67.760) nm with Undoped ZrO2 and ZrO2: 3% Cu respectively, Whilst the root mean-square(rms) roughness from (5.830 - 3.210) nm of Undoped ZrO2 and ZrO2:3.0 % Cu respectively. Eg reduction from 5.2 eV before doping to 5.0 eV after 4% Cu-doping.Whilst absorption coefficient, Refractive Index and extinction coefficient are rising with rising with Cu content with ZrO2 thin films Nanostructured ZrO2 and ZrO2: Cu were prepared employing CSP method. XRD anaylsis assures that ZrO2 offer the formation of crystalline phase with (200) plane by increasing Cu-doping. Crystallite size (D) increases from ( 15.990 -19.780) nm as Copper content increase, whilst strain (ε) decreased from 2.160 to 1.750 , whilst dislocation density (δ) reduction from 3.91 to 2.55.
