摘要： In a thin film electroluminescent element comprising a phosphor thin film, a dielectric thin film disposed on at least one of the surfaces of the phosphor thin film and electrodes for applying a voltage across the thin films, the aforementioned dielectric thin film is formed of a dielectric material expressed by a general formula of AB.sub.2 O.sub.6 (where A represents a divalent metal element and B represents a pentavalent metal element). By employing the dielectric material, the voltage for driving a thin film electroluminescent element can be lowered without decreasing the brightness of the element. Further, by using a composite dielectric thin film in which the dielectric thin film expressed by the aforementioned general formula AB.sub.2 O.sub.6 is laminated with a dielectric thin film which is not susceptible to dielectric breakdown of self-healing type, the composite dielectric thin film is made susceptible to the dielectric breakdown of self-healing type. Additionally, the value of product of the dielectric breakdown field intensity and dielectric constant is increased to obtain a thin film electroluminescent element having excellent characteristics.

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 red emission fluorescent display device employing improved SnO.sub.2 :Eu phosphor as a low-energy-electron excitation phosphor. The phosphor is manufactured by the following steps:To a starting material selected from the group consisting of at least one of metallic tin, stannous and stannic halide and stannous sulfate, europium oxide is added in the amount of 5.times.10.sup.-2 to 10 atomic % europium to tin. The mixture is heated and stirred with nitric acid until it becomes dry due to evaporation of the solvent water and unreacted nitric acid, thereby forming a mixed powder of metastannic acid and europium. Then the powder is subjected to heat treatment, causing the metastannic acid to thermally decompose and the europium to diffuse into the stannic oxide matrix.The device exhibts remarkably high luminescence intensity and it is possible to achieve the intensity of 26f.L or more under the E.sub.b of 10 V and the I.sub.b of 1.5 mA/cm.sup.2.

摘要： A red emission fluorescent display device employing improved SnO.sub.2 :Eu phosphor as a low-energy-electron excitation phosphor. The phosphor is manufactured by the following steps:An aqueous solution of a mixture of europium and at least one material selected from stannous halides and stannous sulfate is prepared. The amount of europium ion is adjusted so that the ratio thereof to tin ions ranges between 5.times.10.sup.-2 and 10 atomic %. The solution is poured into and mixed with a hot aqueous solution including oxalic ions, while the mixed solution is being stirred, to form oxalate coprecipitates of tin and europium. After being dryed the coprecipitate is heated so as to be thermally decomposed and then is subjected to heat treatment at the temperature above that for the thermal decomposition, whereby europium ions are diffused into the stannic oxide matrix.The device exhibits remarkably high luminescence intensity which is satisfactory for practical use.
