Abstract
We were able to fabricate a PDP with an air-stable high-γ material Ca_<0.36>Mg_<0.64>O protective layer. The thickness of the CaCO_3 layer formed on the surface of the CaMgO protective layer during high-temperature process in air was reduced by a new deposition conditions and increasing the concentration of MgO in the CaMgO protective layer. The discharge voltage of the panel stabilizes at low values (V_f=161V, V_<s min>=112V) within 40h of aging; this duration is remarkably short for a high-γ protective layer under the air annealing process.
