Abstract
We have shown that all emission colors can be introduced into a single layer of thin film electroluminescent (TFEL) phosphor by ion implantation. Four colors (RYGB) have been demonstrated in undoped ZnS TFEL panels by ion implanting transition metal and rare earth luminescence centers. Full size ion implanted TFEL panels with red, yellow, and green phosphors have comparable performance to commercial displays with co-evaporated phosphors. Bright blue, green, and weak red electroluminescence have been produced in ion implanted CaGa2S4. Control of activator charge compensation and depth distribution is very important for bright electroluminescence. Ion implantation appears very promising to fabricate full color TFEL displays by a simplified procedure, thus substantially reducing manufacturing costs.
