A group of researchers from Ural Federal University (UrFU), together with colleagues from the Ural Branch of the Russian Academy of Sciences (RAS) and the scientific community in India, have developed a ceramic material that emits red, green, and blue light. These properties can enhance the brightness and clarity of images on displays of mobile phones, tablets, computers, and televisions.
According to the scientists, the material has high strength because it was developed under high pressure and low temperature conditions.
The researchers noted that the pixels we see on displays are miniature color transmission elements. The color spectrum is formed by a combination of three colors: red, green, and blue. In the material developed by the scientists, luminescence is achieved by adding carbon particles.
Nano-ceramics can provide all three primary colors, eliminating the need to use separate LEDs for each of them. Thanks to the material’s strength, defects have been avoided, and optical transparency has been achieved. These characteristics can be useful for the production of displays installed in smartphones, tablets, and televisions.
To create nano-ceramics, researchers used aluminum-magnesium spinel, which has a cubic crystalline structure, preventing light refraction and scattering.
