Abstract


ABSTRACT

 

 

In this work, we have studied the influence of Mn doping on the structural, morphological, optical and photoluminescence (PL) properties of ZnO thin films. ZnO thin films with different concentrations of Manganese (0, 2 and 4 mol.%) were prepared by the sol–gel spin coating process and synthesized on glass substrates. By using an X-ray diffractometer (XRD) (Bruker 8 Advance) with Cu-kα radiation having a wavelength λ=1.5406 A°, the structural properties of the films were characterised. To evaluate the band gap, the optical transmission spectra were measured by an ultraviolet-visible (UV-vis) spectrophotometer (UV-3101 PC-Shimadzu) in the spectral  range 300-800 nm. Photoluminescence (PL) measurements were recorded using a spectrofluorimeter (Perkin Elmer LS 50B) with the excitation wavelength of 325 nm.
