Abstract :
We investigated the impact of atomization treatment by Femto-second laser to improve the luminance properties of distributed-type ZnS inorganic EL devices. The luminance intensity of EL devices with the phosphor irradiated for the some conditions has become five times higher than that with the original phosphor.
