Title: The Innovative Contributions of Masaru Nagai
Introduction
Masaru Nagai is a prominent inventor based in Nagano, Japan. He has made significant contributions to the field of organic electroluminescent devices, holding a total of 5 patents. His work focuses on enhancing the efficiency and functionality of color conversion films and devices.
Latest Patents
Nagai's latest patents include a color conversion film and a multicolor-emitting organic electroluminescent device that incorporates this film. The color conversion film is designed to absorb light emitted from an organic electroluminescent part that emits blue-green light, converting it to visible light at a longer wavelength. This innovative film utilizes two different dyes, where the first dye is a polymer dye with an average molecular weight ranging from 1000 to 1,000,000. This dye absorbs incoming light and transfers its energy to a second dye, which then emits light. The multicolor-emitting device achieves excellent conversion efficiency without increasing the thickness of the color conversion film, a common limitation in conventional devices.
Another notable patent involves a method for fabricating a color conversion layer that realizes high-efficiency color conversion characteristics without significantly increasing the film thickness. This method allows a polymer material with a specific weight-average molecular weight to intrude into the color conversion layer, suppressing concentration quenching and increasing the fluorescence quantum yield.
