Abstract: PROBLEM TO BE SOLVED: To obtain a light source capable of providing the polarized luminescence by forming a first polysilane film on a transparent anode plate by using solvent insoluble polysilane, forming a second polysilane film on the first polysilane film by using a solvent soluble polysilane, and mounting a cathode plate on the second polysilane film. SOLUTION: A polarized luminescence EL element comprises a first polysilane orientation film 2 oriented by a mechanical deposition method and formed on a transparent anode plate 1, a second polysilane orientation film 3 orientated by an epitaxial growing and formed on the first polysilane orientation film 2, and further a cathode plate 4 formed on the second polysilane orientation film 3. By mounting a hole blocking layer 5 between the second polysilane orientation film 3 and the cathode plate 4, the flowing of positive charge to the cathode can be prevented, and the characteristic of the EL element can be further stabilized. By combining two kinds of polysilane orientation films, an uniform orientation film is formed in the element, and the minimized EL element of high efficiency can be provided.

Abstract: PURPOSE:To readily obtain the subject oriented film, capable of selectively absorbing polarized light in a specific direction of ultraviolet rays at a specified wavelength and useful for polarizing filters, etc., by press forming powder of polysilanes, pressing and frictionally extending the formed sheet in one direction on the surface of a smooth transparent unit. CONSTITUTION:This method for producing an oriented film of polysilanes is to press form, e.g. powder of the polysilanes expressed by the formula [R and R are each an alkyl or an aryl; (n) is the polymerization degree], prepare a sheet having preferably about 1-3mm thickness, press and frictionally extend the resultant formed sheet in one direction on the surface of a smooth transparent unit (preferably glass, quartz or a polycarbonate) and form the oriented thin film on the surface. Furthermore, the pressing and frictional extension are preferably carried out by heating the surface of the transparent unit at

Abstract: PROBLEM TO BE SOLVED: To provide a low-cost space light modulating element of small size requiring no light for reading, operating at room temp., and capable of making quick response. SOLUTION: A space light modulating element is configured, so that a photoelectric conversion layer 40 and an electro-luminescent layer 20 are installed opposing each other and a carrier energized by the light exposed on the conversion layer 40 is implanted into the EL layer 20 by an electric field impressed on the layers 40 and 20 so that the light is energized to cause light emission, wherein the layer 20 is made of an organic electro-luminescent material and the layer 40 is made of metal phthalocyanin complex.

Abstract: PURPOSE:To obtain the subject crystal having isotropically high strength, by orienting a specific alkyldiamine perpendicularly on a surface of a substrate, depositing a diamine and a diacetylenedicarboxylic acid by vacuum evaporation and irradiating with ultraviolet ray, etc., to effect the solid-phase polymerization. CONSTITUTION:(A) An alkyldimine of formula I (n is 8-18) (e.g., diaminodecane) is deposited on (B) a substrate such as polished glass plate by vacuum evaporation at a heating temperature of the component A of 30-110 deg.C, a substrate temperature of -30-10 deg.C and a vacuum degree of 10 -10 Torr. Thereafter, (C) a diamine of formula II (R is alkyl, aryl, etc.) and (D) a diacetylenedicarboxylic acid of formula III (R is alkyl, aralkyl, etc.) are deposited on the surface by vacuum evaporation, polymerized and then irradiated with ultraviolet ray or ionizing radiation (e.g., gamma-ray of cobalt 60) to effect the solid-phase polymerization and obtain the objective crystal.
