Abstract:
A surface treatment layer containing alkali metal oxide is formed on at least one of substrates to form a body of a surface light source. The surface treatment layer may be formed of oxide by coating at least one of cesium, potassium, rubidium, and compound thereof on the surface of the substrate and by performing heat treatment to the substrate. The surface treatment layer containing alkali metal oxide easily emits secondary electrons and reduces firing voltage of the surface light source. Black start is improved, discharging efficiency is increased, and heat generated during the operation is decreased.
