Investigation of Nanostructured Zirconium Oxide Films Manufactured by Spray Pyrolysis: Structural, Morphological, and Optical Properties

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.
