    摘要： A technical problem of the present invention is to provide a condensed polycyclic organic pigment having excellent dispersion properties and dispersion stability. More specifically, the technical problem of the present invention is to provide a condensed polycyclic organic pigment in which a practically sufficient viscosity is achieved in terms of both the initial viscosity of a base ink and the viscosity over time of a base ink when used in the printing ink application. As a result of thorough studies on the surface state of organic pigment particles and interaction among components constituting a printing ink, it has been found that the technical problem can be solved by using a polyvalent metal inorganic salt in a condensed polycyclic organic pigment, thus accomplishing the present invention.

    摘要： A color conversion sheet converts incident light into light with a wavelength longer than that of the incident light. The color conversion sheet includes the following layer (A) and layer (B): the layer (A): a layer containing an organic light-emitting material (a) that exhibits light emission with a peak wavelength observed in a region of 500 nm or more and 580 nm or less by using excitation light in a wavelength range of 400 nm or more and 500 nm or less and a binder resin; and the layer (B): a layer containing an organic light-emitting material (b) that exhibits light emission with a peak wavelength observed in a region of 580 nm or more and 750 nm or less by being excited by either or both of excitation light in a wavelength range of 400 nm or more and 500 nm or less and light emission from the organic light-emitting material (a) and a binder resin.

    摘要： This invention is related to novel perylene diester derivatives represented by the general formula (I) or general formula (II) as described herein. The derivatives are useful in various applications, such as luminescent dyes for optical light collection systems, fluorescence-based solar collectors, fluorescence-activated displays, and/or single-molecule spectroscopy. The invention also relates to a luminescent medium, such as a luminescent film, that can significantly enhance the solar harvesting efficiency of thin film CdS/CdTe or CIGS solar cells. The luminescent medium comprises an optically transparent polymer matrix and at least one luminescent dye that comprises a perylene diester derivative. Over 16% of an efficiency enhancement to a CdS/CdTe solar cell and over 12% of an efficiency enhancement to a CIGS solar cell can be achieved.

    摘要： An organic EL device comprises: a light-transmissive substrate; a transparent electrode; an organic emitting layer; and an opposing electrode. A light-extraction layer provided by layering a high refractive index layer adjoining the transparent electrode and a low refractive index layer adjoining the light-transmissive substrate includes recess-protrusion units each provided by a protrusion and a recess at an interface between the high refractive index layer and the low refractive index layer. In at least one of the recess-protrusion units, a distance from the interface between the high refractive index layer and the low refractive index layer to an interface between the transparent electrode and the high refractive index layer is equal to or more than an optical coherence length and a height of the protrusion, a width of the protrusion and a gap between the protrusion and another protrusion adjoining the protrusion across the recess is 1 μm or more.
