P‐88: Effect of ZnS Treatment by Plasma on Properties of Derived Phosphors

Abstract

Influence of some parameters of plasma treatment of initial ZnS powder precursor on properties of derived phosphors has been investigated. for this we processed ZnS powder precursor with different parameters of plasma treatment: gases, different times and electric potentials. Electroluminescent phosphors were then synthesized using treated ZnS and EL devices were fabricated. Plasma treatment increased EL and PL brightness and also increased intensity of green band in emission spectra comparing to blue one.
