Influence of Mn-doping on The Structure Properties of ZnO:Mn Thin Films
ZnO:Mn thin films with different Mn concentration were prepared on glass substrates at room temperature using RF magnetron sputtering method. Raman spectroscopy
X-ray diffraction spectra and SEM were used to analyze the structural characteristics of the ZnO:Mn films. The results show that ZnO:Mn thin films have significant wurtzite structure with Mn doping mole fraction from 0 up to 5.6%. The redshift of Raman peaks at 437 cm
-1
and 527 cm
-1
can be explained by the lattice defects and disorder induced by the increasing of Mn concentration. The appearance of Raman spectra at 647 cm
-1
indicates the formation of MnO
leading to the worse crystallization of ZnO:Mn films
which is also evidenced by XRD and SEM results.
