Color characterizations of pure ZnO and ZnO-SeO2 thin films annealed at different temperature

Abstract EN

Pure zinc oxide and ZNO / SEO2 oxide thin films were prepared successfully by sol gel method and annealed at different temperature under ambient condition.

these films were characterized by means of XRD, AFM, and UV-visible.

XRD patterns clearly showed the presence of crystalline ZNO / SEO2 particles, the zno / seo2 film showed a good crystallinity like pure ZNO film, optical transmittance spectra of films showed high transparency (> 87%) in visible region.

the color coordinate and tristimulus value of transmittance spectral showed that the best decolourization result was achieved at 7.5 at.% se at 400oc, 600oc and 10 at.% se at 500oc, for the best brightness result appeared at two point with 2.5 at.% se at 600oc and 7.5 at.% se at 400oc.

AFM studies reveal that RMS roughness of the thin films increased with the increasing of se concentrations.

also, the surface roughness increased with the increasing of the annealed temperature.
