Abstract

In this Study, Copper oxide films were deposited on the glass substrates
heated at different temperatures of (623,673,723,773)K by Spray Pyrolysis
technique. The effect of substrate temperature on the structural properties
and electronic transitions of the films was estimated. The XRD results
showed that all the prepared films were polycrystalline, monoclinic crystal
structure with a preferred orientation along (1?
11). The average crystallite
size was increased from (12nm) to (19nm) with increasing of substrate
temperature, also atomic force microscope (AFM) images showed the grain
size increased from (74.5nm) to (99) as well as the average surface
roughness and root mean square value (RMS) of the films increased with
increasing substrate temperature expect values at atemperature of (723K)
from these results we conclude that these films have some nanostructure for
transition was decrease from (2.11eV) to (2.01eV) by increasing substrate
prepared films. and The optical energy gap for allowed direct electronic
temperature.
