摘要： The development of a dielectric thin-film which is high (140 MV/cm or above) in product of dielectric constant .epsilon..sub.i and dielectric breakdown field strength E.sub.ib is essential for realizing an EL element which can operate stably at a low voltage. Such dielectric film is also required which can withstand heat treatments at high temperatures above 500.degree. C. and is proof against clouding and in which the electrical breakdown caused by a minute fault produced in the process of film formation is self-healed. A film material which satisfies all of these requirements could be obtained from a TiO.sub.2 -BaO based composition by partially substituting the position of Ti with Sn, Zr or Hf and also partially substituting the position of Ba with Ca or Mg. By using these dielectric films, it is possible to obtain a low-voltage drive thin-film electroluminescent element which are high in production yield and reliability.

摘要： A phosphor is formed with a glass coating layer on a surface of a phosphor grain to have improved moisture and/or thermal stability. A method for manufacturing the phosphor comprises preparing phosphor grains excitable by light, and forming a glass coating layer on a surface of each phosphor grain. The glass coating layer may be formed by mixing the phosphor grains with a glass composition; heat-treating a mixture of the phosphor grains and the glass composition to make the glass composition melt and surround the phosphor grains; and cooling and breaking the heat-treated mixture to provide phosphors, each comprising the phosphor grain having the glass coating layer formed on a surface of the phosphor grain.
