Abstract
A thin film electroluminescent device is disclosed which includes an electroluminescent emitting layer comprising an alkaline-earth selenide, such as SrSe (strontium selenide) and calcium selenide (CaSe), or an alkaline-earth sulfide, such as CaS (calcium sulfide) and strontium sulfide (SrS), as the luminescent host material, and a lanthanoid rare-earth element as an activator, and a method of fabricating the same is also disclosed.
