Tohoku Univ. Technology : “Black body” with nano-micro size metal protuberance and its manufacturing method : T12-022
Capable of absorbing more than 95% of “ultraviolet” to “visible” to “infrared” light!
“Black bodies” are substances that can completely absorb all kinds of light, and carbon nanotube (CNT) black bodies are known as substances that can almost completely absorb light. CNT black bodies can absorb more than 98% of light (electromagnetic waves) in a wide wavelength range of 200 nm-200μm from “ultraviolet” to “visible” to “far-infrared” light. CNT black bodies can be used for shielding cameras and optical equipment, infrared absorbers, thermal infrared sensors, and cooling electronic equipment. However, CNT black bodies are fine powders, and there have been some problems such as difficulties in manufacturing and handling them. This invention provides a nano-micro metal “black body” capable of absorbing light over a wide wavelength range from “ultraviolet” to “visible” to “infrared” light, and capable of selectively adjusting the absorption direction of light.
