What is the News?
Scientists have developed a material through which we can move towards bright, stable and affordable light-emitting diodes(LEDs).
What are LEDs?
LED is a semiconductor device that emits infrared or visible light when charged with an electric current.
Cost-efficient and bright light-emitting diodes(LEDs) are commonly desired for general light sources. However, attaining desired stability and brightness of LEDs has been challenging for scientists.
What has been developed now?
Scientists at the Center for Nano and Soft Matter Sciences(CeNS), an autonomous research institute under the Department of Science and Technology(DST) found that simple plasma treatment of inorganic material of cesium lead halide nanocrystals can lead to an enhanced stabilization of many folds showing the promise of bright and stable LEDs.
Note: Plasma treatment induces the cross-linking of the organic molecules, oleylamine, present on the surface of the nanocrystals. This creates a stronger network of ligands, providing better encapsulation and higher PL intensity.
