- Abstract
- The picture quality of a plasma display panel is very sensitive to the phosphor characteristics such as decay time, surface state, and even longevity of phosphor material in itself. In this work, material characteristics of Zn2SiO4:Mn, Y2O3-coated Zn 2SiO4:Mn, and YBO3:Tb, which are dominant in commercial application, were examined for investigating the aging characteristics of green PDP phosphors. It was found that Y2O 3-coated Zn2SiO4:Mn are easily degraded at high temperature. However, all the samples were very weak after vacuum annealing. The luminescence intensity was decreased by order of one magnitude.
