“…The increase of defects density states leads to increase the non-radiative recombination centers and thus resulting in reduction of emission intensity [28]. Deepa et al also noticed similar reduction of emission intensity in Mn doped ZnO thin films with the increase of Mn doping concentration [29].…”

“…Transition metal doped ZnO has been one of the most promising materials for room temperature ferromagnetism. Replacement of Zn by Mn should not cause a significant change in lattice constant because the ionic radii Mn 2+ (0.80Å) is similar to that of Zn 2+ (0.74Å) [4]. Work from other researchers show that by doping ZnO with Mn, the band gap reduces for low concentration doping (below 3%) and the band gap increases at higher concentrations because the band gap MnO is around 4.2eV [5].…”

Undoped and Mn doped ZnO films with different doping concentration were synthesized by sol gel method using a spin coating technique. Zn 1-x Mn x O thin films are prepared using 2-methoxyethanol solution of zinc acetate dehydrate and manganese acetate tetrahydrate. The solution was stabilized by MEA. The quantity of Mn in the sol was varied from x = 0, 0.02 and 0.04 with annealing temperature of 700ºC. The samples were characterized using AFM to investigate the surface morphology and nanostructures. The XRD analysis shows the crystalline structure and orientation of the films. The films exhibit hexagonal wurtzite structure and improved crystalline quality by increasing the Mn doping.Meanwhile, the optical properties were characterized using UV-Vis where the transmittance and band gap decreases upon increment of Mn concentration.

The morphology and optical properties of Zn 1-x Mn x O films were synthesized by sol gel method using spin coating technique. Zn 1-x Mn x O thin films is prepared using 2methoxyethanol solution of zinc acetate dehydrate and manganese acetate tetrahydrate. The solution is stabilized by MEA. The quantity of Mn in the sol was varied from x = 0, 0.02, 0.04, 0.06 and 0.08 with annealing temperature of 600ºC. Investigation of the physical properties and presence of nanostructures were executed using SEM and XRD characterization. Addition of Mn lead to the formation of nanosize rod structures.The optical properties were characterized using UV-Vis where the band gap and transmittance can be determined. Results show that the transmittance spectra and band gap reduces after a certain percentage of Mn addition. The variation of the band gap performance with dopant concentration is also examined.
