Abstract

SrS-ZnS multilayered thin films are proposed as novel thin film electroluminescent (EL) phosphors. Recent advances in the development of (SrS:Ce/ZnS) n multilayered thin film EL devices are summarized. Growth of (SrS/ZnS) n multilayered thin films by using the hot wall technique, which enables us to grow ZnS and SrS thin films at the same substrate temperature and then to prepare (SrS/ZnS) n thin films having a large number of ZnS and SrS films, is discussed. Features and problems of ZnS and SrS thin film EL phosphors are also discussed.
