Developed a material that emits white light at room temperature - promises to greatly simplify lighting
Xinhua News Agency, Tokyo, May 15th The Japan Institute of Materials and Materials Research said on the 14th that researchers at the agency have developed a material that can emit white light at room temperature. This material has a simple production process and can be applied to various shapes. On the surface of the material, the new material is expected to be a next-generation luminescent material that greatly simplifies the manufacturing process of lighting devices and the like.
According to a press release issued by the Institute of Substances and Materials on the 14th, the power consumption of lighting devices accounts for 20% of our total electricity consumption. In order to reduce greenhouse gas emissions, people urgently need to innovate materials and technologies in the lighting field. White light-emitting organic materials have attracted attention because they can replace incandescent and fluorescent lamps as light source materials for next-generation lighting. However, once some of the existing organic materials are applied to the substrate and the solvent is evaporated, the molecules in the luminescent material will agglutinate with each other, resulting in insufficient luminescence performance.
Senior researcher at the Institute of Substances and Materials Research, Hideki Nishikawa and others first developed a fluorescent liquid that does not agglutinate and does not volatilize. This liquid can emit blue fluorescence without the need for volatile organic solvents. A small amount of powdered fluorescent material is added to make a paste-like material that emits high-brightness white light.
According to the communique, the new luminescent material has a simple production process and is applicable to various shapes of substrates. Moreover, this material can be adjusted to emit full-color light, which is expected to become a new material in the next generation of printable electronics.
The relevant papers are scheduled to be published in the German "Applied Chemistry International Edition" and the British "Nature" magazine.
