| Abstract: | The Cd1-xMn xSe thin films were grown from elemental selenium, sodium sulphite, cadmium chloride and MnCl2, onto glass substrates by a solution growth technique. As-deposited films were annealed at 600 K. The optical absorption of annealed Cd1-xMn xSe thin films with different values or composition parameter x was then studied in the energy range from 1.10 to 4.0 eV. The Cd0.5Mn0.5Se film showed allowed direct optical band gap with a room temperature gap or 1.58 ± 0.01 eV. Another direct transition observed in these films with x = 0.2, 0.3, 0.7 and 0.9 is ascribed to an optical transition from the crystal field spilt, valence band to the conduction band minimum. A third direct allowed transition from the spin-orbit valence band to the Conduction band is also observed in x = 0.2, 0.3, 0.7 and 0.9 films. |
