Abstract: Provided are a photon up-conversion film, which is capable, of high-efficiency up-conversion even in air and even when low-intensity light is used, and a simple method of producing the film. The photon up-conversion film according to one embodiment of the present invention includes: a matrix including a resin; and a pore portion, wherein the photon up-conversion film includes at least a sensitizing component capable of absorbing light in a first wavelength region λ1, and a light-emitting component capable of radiating light in a second wavelength region λ2 including wavelengths shorter than those of the first wavelength region λ1, and wherein the sensitizing component and the light-emitting component are present at an interface between the matrix and the pore portion.

Abstract: Provided are a novel solid-based upconversion film having high emission efficiency and a method for producing the upconversion film. An upconversion film according to the present invention is a stretched film formed of a composition at least including an acceptor, a donor, and a matrix resin, wherein the matrix resin is a poly(vinyl alcohol)-based resin, and the matrix resin is oriented by stretching. A method for producing an upconversion film according to the present invention is a method for producing a photon upconversion film including a step of stretching a composition at least including an acceptor, a donor, and a matrix resin, wherein the matrix resin is a poly(vinyl alcohol)-based resin, and the stretching is wet-stretching in an aqueous solution of boric acid.

Abstract: Outer plates have a doughnut-like disk shape and are attached to the inner circumferential surface of a case member. On the other hand, inner plates have a substantially arc shape and are swingably supported about a position at a distance from the center of rotation of a shaft. The inner plates are held at a first position, at which the interlocking area between the outer plates and the inner plates is small, by a tension coil spring when the relative rotational speed between the case member and the shaft is small, and, when the relative rotational speed between the case member and the shaft exceeds a predetermined value are pivotally moved toward the outer plates by the shearing force of a viscous fluid and held at a second position at which the interlocking area between the movable plates and the first plates is large.
