This work considers a Mn-doped ZnO (ZnO:Mn) film deposited on a slide glass substrate by ultrasonic spray pyrolysis. ZnO:Mn (Mn at 1.5 at%) film with and without an applied magnetic field, is demonstrated to have absorption edges at 2.74 and 2.84 eV, respectively. These values are lower than that of a pure ZnO film because the Mn-doping causes the exchange of s-d and p-d interactions or high carrier concentration. When the ZnO:Mn film is placed in a magnetic field B z of 0.5 T, an absorption edge and a photoluminescence (PL) shift of about 0.1 eV and 85 meV, respectively, are observed. This shift is attributed to the interband magneto-optic absorption associated with the Landau splitting. The observed shift increases with the amount of Mn dopant. © 2011 Elsevier Ltd.
