Thermal Degradation of Blue-Emitting BaMgAI_(10)O_(17):Eu~(2+) Phosphors for Plasma Displays

摘要

Thermal luminance degradation of blue-emitting BaMgAI_(10)O_(17):Eu~(2+) phosphor has been investigated in a baking process for the manufacture of plasma display panels. The degradation behavior of the phosphor paste is similar to that of powder phosphorafterbaking in deoxidized atmosphere (in 100%N_2 flow) and shows the remarkable reduction of the efficiency in 140-200nm wavelength region.
