| Abstract(in English) | ZnAl_2O_4:Mn is known as a phosphor which shows green emission peaked around 510nm. This emission peak is known as a typical narrow emission for Mn^<2+> represented luminescent center of Zn_2SiO_4:Mn and ZnGa_2O_4:Mn. However, it has not been studied sufficiently that the photo and cathode luminescent properties of ZnAl_2O_4:Mn phosphor then, in this study, structural and luminescent properties of ZnAl_2O_4 powder synthesized by citric acid gel method were investigated. Firing temperature was changed from 800 to 1200℃ and Mn content was maintained up to 2 mol%. From the results of CL measurements, green emission of Mn^<2+> with the main peaked at 512nm and broad red emission peaked around 700nm from host material are observed. The highest luminous efficiency of 1.1lm/W was obtained for the powder fired at 1200℃ under an anode voltage of 4kV and an electron-beam density of 60μA/cm^2. |
