🔆What is hematene?

✅Nanoflakes of a material called hematene extracted from iron ore have been found capable of withstanding and acting as shield from high laser intensities.

✅Hence it could be used to make devices called optical limiters that can protect sensitive optical equipment from light-induced damage.

✅Radiation from laser sources is highly concentrated and powerful and can be detrimental to sensitive equipment such as sensors, detectors, and other optical devices.

✅When the input intensity increases optical limiters control the amount of light that passes through, thereby preventing damage to the optical component.

✅These devices are often useful in laser technologies, military, telecommunications, aircrafts, and scientific research in several ways.

✅They found that 2D nanoflakes of hematene is capable of withstanding very high laser intensities, and they exhibited excellent optical limiting of green laser light while maintaining a high linear transmission for low-intensity light.
