Abstract
Europium activated yttrium oxide ($Y_2O_3$ : Eu) is extensively applied to red phosphor for Flat Panel Display because of its high efficiency and the thermal and chemical stability. Flat Panel Display screen which have a high resolution and high efficiency needs to the phosphors of ideally small size spherical particle. In this study, we prepared a $Y_2O_3$ : Eu phosphor using polymeric precursor methods and investigated the codoping effect by introducing the group 1 or 2 elements to $Y_2O_3$ : Eu phosphor in view of improvement of luminance efficiency.
