We report nitrogen plasma modification of the ZnS: Cu, Br electroluminescence phosphor. Modification resulted in 30% improvement of ZnS: Cu, Al EL brightness at 220V drive. In the same time emission peak shifted of from 486 to 504nm due to increase of relative intensity of green band in EL spectrum. Thus plasma treatment is a perspective method for the control of EL brightness and spectra of ZnS phosphors.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
