A team of material engineers from Kobe University has developed a new approach to color production using silicon nanospheres. These particles have the ability to scatter light in bright colors and can be easily controlled by varying their size. The suspension of these nanospheres can be applied to surfaces, creating a structural color that is not dependent on viewing angle. This new technology has the potential to revolutionize color production and can be applied in various industries.

As technology continues to advance, researchers are always looking for new and innovative ways to improve our everyday lives. One area of focus has been color production, which has always been limited by traditional pigments that can degrade over time. However, a team of material engineers from Kobe University in Japan has developed a new approach to producing colors using silicon nanospheres.The researchers, FUJII Minoru and SUGIMOTO Hiroshi, have been working on this project since 2020 when they first achieved precise particle size control and developed colloidal suspensions of spherical and crystalline silicon nanoparticles .

These tiny particles have the ability to scatter light in bright colors due to a phenomenon called 'Mie resonance.' This means that by varying the size of the particles, the color that is mainly reflected from the suspension can be easily controlled.In their recent publication in the journal ACS Applied Nano Materials, Fujii and Sugimoto demonstrate that the suspension of silicon nanospheres can also be applied to surfaces, creating a new form of structural color that is not dependent on viewing angle .

This is a significant advancement because traditional structural colors are often viewed as iridescent and can only be seen from a specific angle.This new approach of using silicon nanospheres for color production has many advantages over traditional methods. Not only does it eliminate the issue of viewing angle dependence, but it also produces colors that do not fade over time. Additionally, a single layer of these nanospheres, with a thickness of only 100-200 nanometers, can weigh less than half a gram per square meter, making it one of the lightest color coats in the world .

In conclusion, the development of structural coloration using silicon nanospheres has the potential to revolutionize the way we produce and use color in our daily lives. Its lightweight, durable, and versatile nature makes it a promising alternative to traditional pigments and could lead to new applications in various industries.
