Abstract
In this paper, we present the photoluminescence (PL) characteristics of plasma display panel (PDP) phosphors under Xe-He-Ne gas discharge. Under high Xe-content gas discharge, PL intensity of the phosphors significantly enhanced due to the increased 173-nm excitation light. By analyzing the PL properties of the phosphors, it was shown that the luminescence saturation phenomenon greatly influences the PL intensity of PDP phosphor under high Xe-content gas discharge.
