摘要： PURPOSE:To obtain a thin-film light emitting element which can give a high brightness, by bringing oxygen into a state which does not adversely affect light emission by adding an element having a large free energy of oxide formation. CONSTITUTION:In the production of a thin-film light emitting element composed of a substrate and electrodes, an insulation layer and a light-emitting layer laid on the base, the light-emitting layer is formed by the thin film formation process by using a mixture containing an activator selected from among a matrix powder comprising a simple substance, sulfide, phosphide, etc., of a metal of a light emitting ion element and an additive selected from a metal (A) which forms an oxide having a free energy of oxide formation (at room temperature) more negative than that of an alkaline earth element and a sulfide (B) which can satisfy the unequalities of GS.M>GS.H>GO.M [wherein GS.H is the free energy of formation of an alkaline earth metal sulfide (at room temperature) and GO.M and GS.M are the free energies of formation of the oxide and sulfide of a certain element (at room temperature) (similar phosphide, halide or the like can also be used)] as a target. In this way, the light emitting layer can be composed of a matrix layer comprising the alkaline earth metal sulfide, the light emitting ion and an oxide phase present in a high concentration in the grain boundaries in the matrix phase.

摘要： PURPOSE:To stabilize the time-wise fluctuations in EL luminescent characteristics by constructing part or all of a first insulation layer and/or a second insulation layer with a film made of a fluoride of alkaline metal and also by permitting this film to come in contact with a light emitting layer. CONSTITUTION:On a 1mm thick glass plate 1, ITO is formed as thick as 0.52mum as a lower-part transparent electrode 2 by sputtering and then photo-etched into a stripe shape. On this electrode, a first insulation layer 3 made of Ta2O5 is formed as thick as 0.1mum by sputtering and also, a lithium-fluoride(LiF) film 6 is formed as thick as 0.1mum by the electron-beam evaporation method. On this film, as a light emitting layer 4 CaS:Eu is formed as thick as about 1mum by the electron-beam evaporation method and then a second insulation layer 3 made of a LiF film 6 of Ta2O5 is formed again and finally, as an upper-part electrode Al is formed by resistance-heating evaporation. With this, it is possible to prevent oxygen from being diffused into the light emitting layer.

摘要： PURPOSE:To stabilize a driving characteristic of an EL element and to improve its breaking strength by using a PN film or a PNO film for the EL element. CONSTITUTION:A PN or a PNO film is used as an insulating film of an EL element. In order to use the film as the insulating film of the EL element, a performance index, which can be obtained by a product of dielectric constantepsilonoepsilonr above 1muC/cm and breakdown electric field strength EBD, is required, while the PNO film is applicable in the range of oxygen content 0-50atom%. For example, the EL element using a P6N5O3 film has the highest breakdown voltage while having large difference between luminance starting voltage and breakdown voltage so as to be hard to be broken. Thereby, breakdown voltage of a thin film EL element can be heightened and the EL element hard to be broken can be formed.

摘要： PURPOSE:To solidify a molten metal at nonuniform rates of solidification and to obtain a light-gauge strip having axial crystal or fine crystal grains by disposing partially materials having the heat conductivity of the value different form the heat conductivity of a roll material on the rotating and cooling surface of the roll. CONSTITUTION:The white part in the expanded view of a roll surface is the part where a roll material is exposed on the surface and black spots are the points where BN is embedded into the roll. The part 2 in the model diagram showing the section of the light-gauge strip corresponds to the BN part of the roll surface and the part 3 corresponds to the part where the roll material is exposed on the roll surface. The crystal grains beginning to crystallize and grow from the part 2 of BN have the smaller heat conductivity than the roll material and grow therefore to the smaller grains than the crystal of the part 3. The crystal grains of the part 3 on the contrary have a higher rate of solidification and grow to the grains larger than the crystal grains of the part 2 but there are the small crystal grains of the part 2 near said part and therefore the crystal grains grow by bending so as to cover the above-mentioned crystal grains and are parted in the midway of the growth, by which the smaller crystal grains 4 are formed.

Such steel is then subjected to a preliminary aging treatment in a temp. range of 350W650°C to cause precipitation hardening and is thereafter subjected to secondary cold working at 40W75% reduction of area and further a final aging treatment in a temp. range of 500W 560°C. The maraging steel having ≥300kg/mm
2 tensile strength at a room temp., ≥0.6% tensile elongation at a room temp. and having malleability is thus obtd.
