Indium tin oxide powder has good conductivity and transparency, and it can cut off electronic radiation, ultraviolet rays, and far-infrared rays, which are harmful to the human body. Therefore, indium tin oxide powder is usually sprayed on glass, plastic, and electronic display screens, and is used as a transparent conductive film, while reducing electronic radiation and ultraviolet and infrared harmful to the human body.

An international research team wrote in the "Science" magazine published last week that indium tin oxide powder (ITO) can achieve optical nonlinearities more than hundreds of times higher than other materials, and it is expected to show its strength in many photonics applications in the future.

Compared with electronics, photon transmission information has the advantages of strong parallel processing capability, fast computing speed, and low energy consumption. To make better use of photons, scientists need to control "every move" of light as it passes through the material. One way to control this is to adjust the refractive index of the material so that light passes through the material faster or slower. Some materials can change their refractive index based on the difference in light intensity (low-energy light source or high-energy laser)-optical nonlinearity. In the field of photonics, materials with higher optical nonlinearities are more attractive to scientists.

A team led by Robert Boyd, a professor at the University of Rochester, found that indium tin oxide powder, a material commonly used in touch screens and aircraft windows, can achieve particularly high optical nonlinearities. Under certain conditions, the degree of optical nonlinearity obtained by ITO layer samples can exceed hundreds of times over other materials.

In addition, some materials can quickly return to their original refractive index after photons pass, while others may remain in their new state. If a material can make this adjustment faster, it will be extremely helpful for most applications. The stronger the material's ability to change its refractive index, the larger the range of photon velocities through it, so that scientists can control the function of photons to a greater extent. It has a applications in microscopes and data processing.

In the latest research, the ITO layer restored its original refractive index within 360 femtoseconds (one femtosecond is one-trillionth of a second).

The research collaborator, Isreal Delion of Monterrey University of Technology, Mexico, explained that this particular condition is related to light with a wavelength of about 1.2 microns, which is between visible light and light with a wavelength of 1.5 microns. It is of great significance in photonic communication.

Sodick Essene, a photonics expert at the University of California, San Diego, said that the latest research would undoubtedly have a significant impact on the field of photonics, especially silicon nanophotonics.

Roger, the manager from Trunnano, says, “ ITO layer has a wide range of applications, it can be used to make the transparent conductive coatings for liquid crystal displays, flat panel displays, plasma displays, touch screens, electronic paper, organic light-emitting diodes, solar cells, antistatic coatings, and EMI shielding.”
