Abstract: PROBLEM TO BE SOLVED: To provide an organic EL element in which light can be emitted with low voltage and high luminance, and the deterioration of an organic layer can be suppressed by treating the surface of an electrode with a prescribed coupling agent, and providing the organic layer on this surface. SOLUTION: An ITO transparent electrode (anode) 5 is formed on a glass substrate 6, and an EL element forming cell masked by Si evaporation excluding a light emitting area of 2×2mm (arrangement) is formed. The surface of the substrate 6 (the ITO electrode surface exposed between SiO2 ) is treated with a titanate coupling agent containing a hydrophobic group P in the terminal. TPD is evaporated on the surface to form a held transport layer 4. An organic light emitting material (Al-quinoline complex) is evaporated thereon by use of a mask to form a light emitting layer 3 used also as an electron transport layer 2, and Al is then formed as cathode electrode 1, whereby an organic EL element 9 is formed.

Abstract: PURPOSE:To make it possible to store the recording information quantity of about 4 times the present recording information quantity to an optical recording medium of the same size without subjecting the device side to a drastic change, such as shortening of the wavelength of reproducing light, increasing of the numerical aperture NA of a focusing lens and changing of a signal demodulation system. CONSTITUTION:At least a saturable absorbent dyestuff-contg. layer 2 formed by a vacuum thin film forming method and a reflection layer 4 are formed on a light transmissive substrate 1 formed with the recording patterns corresponding to information signals as rugged 1a, 1b shapes. Further, a short-wavelength shift layer 3 which shifts the minimal point of the light reflection spectra of the optical recording medium to a short wavelength side is disposed between the saturable absorbent dyestuff-contg. layer 2 and the reflection layer 4. As a result, the recording patterns inscribed on the substrate 1 are correctly traced on the saturable absorbent dyestuff-contg. layer 2 and the reflection layer 4 and the reflectivity is confined within an adequate rate. Then, the optical recording medium exhibits excellent ultra-definition and good reproduced signals are obtd. from the fine recording patterns formed with micropits at a period shorter than the diffraction threshold lambda/2NA of a reproducing optical system.

Abstract: PURPOSE:To provide carbon tubes made of a fullerene in high yield. CONSTITUTION:This method for producing carbon tubes is to fill a metal or its compound as a simple substance in the interior of an electrode graphite (3a) or mix the metal or its compound with a readily graphitizable carbon, fill the resultant mixture therein, bake the metal or its compound or the mixture, subsequently use the prepared electrode as a positive pole 3, use high-purity graphite as a negative pole 2, carry out the arc discharge in a vacuum chamber and separate the objective carbon tubes from a deposit formed on the negative pole 2. The metal is a transition metal such as vanadium, lanthanum, hafnium or gadolinium or a compound thereof. Thereby, rodlike or needlelike carbon tubes having 1-5mum outside diameter and >=20mum length or carbon nanotubes having 1-10nm outside diameter are obtained.
