Preparation and study of optical absorpation proparties of Zinc-Manganes oxide films

Abstract EN

Amorphous and crystalline thin (Zn-Mn) compound oxide films were prepared on silicon and glass substrates have been characterised by UV-VIS absorption spectroscopy, energy dispersion X-ray fluorescence (EDXRF) and X-ray diffraction (XRD).

The XRF spectrum was used to determine the weight fraction ratio of Zn to Mn in the prepared samples.

XRD shows that air-annealed films at 600 ˚C for 20 minutes crystallises forming a coexistence of three types of oxides that are cubic-Mn20s, cubic Mns04 like structure, and a spiral he aerolite compound ZnMn2C>4 like structure.

The results show that metal zinc is totally diffused into Mn oxide grains.

The spectral normal transmittance T(X) and reflectance R (A) was measured in the fundamental absorption region for amorphous and crystalline compound-oxide films and the spectral refractive index and extinction coefficient were determined.

The optical studies determine the optical bingos of the prepared samples to be 3.26 ± 0.1 for both amorphous and crystalline samples.
