ZnGa2 O 4 : Mn phosphors for Thin-Film Electroluminescent Displays Exhibiting Improved Brightness

Thin films of ZnGa2O4:Mn films have been deposited by radio frequency magnetron sputtering in order to study the effects of annealing temperatures less than 1000°C on the thin-film electroluminescent properties. Energy-dispersive X-ray compositional analysis showed a loss of zinc during sputtering, with the film composition being Zn0.9Mn0.03Ga2O4. All films showed strong (111) and (222) X-ray reflections relative to the power standard. As the …
