    摘要: A thin film electroluminescence device comprising an electrode layer, an emitting layer and an electrode layer formed on a substrate one over another, and an insulating layer optionally interposed between the three layers, the emitting layer being made of CaS serving as a host material and doped with Eu.sup.2+ providing luminescent centers.The emitting layer comprising a novel combination of host material and luminescent center produces a red electroluminescence with a high brightness.
