A highly reflective light-guide system has a highly reflective light-guide surface for reflecting light that has been emitted from a sample and has entered from an entry port opposing a window material and propagating the same to an exit port opposing a light reception surface of a photodetector. An optical filter is provided in a space surrounded by the window material, the photodetector, and the highly reflective light-guide system and transmits the signal luminescence to be measured that is emitted from the sample between the window material and photodetector. The optical filter is fixed to the window material or photodetector by an adhesive, and the peripheral shape of the optical filter is smaller than the shape of the inside of a fitting part to which the optical filter is fitted and that is formed on the highly reflective light-guide system.

Detection device for luminescence analysis and automated analyzer

An analyzing device of the present invention is provided with a flow chamber that a fluid including magnetic particles associated with a labeling substance flows from a fluid inlet to a fluid outlet, magnetic trap means to apply a magnetic field for trapping the magnetic particles to the fluid in the flow chamber, a working electrode and a counter electrode to apply a voltage to the magnetic particles trapped by the magnetic trap means, and to emit a luminescence, a light detection element to detect a luminescence derived from the labeling substance on the magnetic particles trapped in the flow chamber, and regulating means to regulate a region that the light detection element detects the luminescence derived from the labeling substance on a part of magnetic particles of them trapped by the magnetic trap means.

In order to achieve the increased efficiency of an organic light-emitting element, there is a need to reduce the influence of non-radiative recombination of electron-hole pairs except for surface plasmon polariton excitation, to convert most of exciton energy into visible light, and to tremendously improve the luminous efficiency of the organic light-emitting element. An organic light-emitting element according to the present invention includes a reflective electrode, a transparent electrode, and a light-emitting layer placed between the reflective electrode and the transparent electrode, and the organic light-emitting element is configured so that the light-emitting layer contains a host and a first dopant, and for the first dopant, one of the vertical component and horizontal component of the average value for transition dipole moments with respect to a substrate surface is larger than the other of the components.

Organic light-emitting element, light source device and method of manufacturing organic light-emitting element

An object of the present invention is to provide an organic light-emitting device, wherein light trapped in a substrate due to total reflection at the interface between air and a substrate is efficiently extracted to the air side. The organic light-emitting device includes: a transparent electrode; a counter electrode; a light-emitting layer interposed between the transparent electrode and the counter electrode; a front substrate which allows light from the light-emitting layer to exit to the outside from a surface of the front substrate on the opposite side to the light-emitting layer side; and a diffuse reflector which reflects light from the light-emitting layer, wherein the diffuse reflector is provided on a side surface of the front substrate and at a given position on a surface thereof.
