Method of making electroluminescent phosphor

A method for improving the half-life of a zinc sulfide-base electroluminescent phosphor, utilizes the steps of; charging phosphor particles into a reaction vessel; fluidizing the particles with an inert gas; heating the reaction vessel and its contents to 200° C.; introducing hexakis(dimethylamido)d...

Zusammenfassung:	A method for improving the half-life of a zinc sulfide-base electroluminescent phosphor, utilizes the steps of; charging phosphor particles into a reaction vessel; fluidizing the particles with an inert gas; heating the reaction vessel and its contents to 200° C.; introducing hexakis(dimethylamido)dialuminum into the reaction vessel; and reacting the hexakis(dimethylamido)dialuminum with the phosphor particles for 10 minutes.
