摘要:
An opto-magnetic recording medium comprises a recording layer formed of a magnetic film having a readily magnetizable axis in a direction perpendicular to the surface of the film, and a reflective and phase modulating layer provided in contact with the recording layer. The reflective and phase modulating layer is formed so that the imaginary number portion (k) of the refractive index gradually increases in the direction of thickness away from that side which is in contact with the recording layer.
摘要:
There is disclosed an optical recording medium provided with an optical recording layer on a substrate, in which a layer of nitride of a substance selected from tungsten, zirconium, titanium, niobium, vanadium, tantalum and chromium is formed on a side or both sides of the optical recording layer.
摘要:
An optical recording medium comprising a substrate, an optomagnetic recording layer made of a magnetic film where information can be recorded and reproduced by irradiation with a light beam, and an optical recording layer which can be modified in optical properties to form guide tracks when information is recorded in or reproduced from the optomagnetic recording layer.

There is provided an organic light-emitting apparatus in which the luminance can be improved, and, at the same time, the reflection of ambient light can be reduced by adding a prism member and a light-absorbing member to a spontaneous light-emitting device such as an organic light-emitting device, and which includes: a plurality of organic light-emitting devices each having a pair of electrodes and an organic compound layer formed between the pair of electrodes; a prism member disposed on a light extraction side of the organic light-emitting device, an interface on the light extraction side of the prism member being an interface with air; and a light-absorbing member formed between the plurality of organic light-emitting devices, around the prism member, and on a side portion of a protrusion of the prism member.
摘要:
The present invention provides an light-emitting element in which an organic compound layer containing a carbonate, for example Cs2CO3 and Li2CO3, as a dopant is in substantially electrical contact with a cathode by providing an organic compound layer having a dopant easy in handling so as to bring the organic compound layer into contact with the cathode. The light-emitting element includes a pair of electrodes sandwiching the organic compound layer, which is a co-evaporation layer of an organic compound and the carbonate.
