CeNS Research Team’s new material developments will help us create more stable LEDs that can emit very bright light.

Plasma treatment of inorganic cesium lead halide nanocrystals can significantly increase stabilization, indicating the potential for bright and stable LEDs. The team has also filed a provisional Indian patent for their discovery and is actively seeking commercialization partners.

  • Plasma treatment of some inorganic nanomaterials has demonstrated the path to bright, stable, and cost-effective light-emitting diodes (LEDs)
  • Scientists from the Centre for Nano and Soft Matter Sciences (CeNS), an autonomous research institute affiliated with the Department of Science and Technology (DST), discovered that simple plasma treatment of inorganic cesium lead halide nanocrystals.

Plasma-induced stabilization of small inorganic nanocrystals is expected to help create bright and stable LEDs that will allow us to create bright and durable lights in the future.

LEDs are increasingly being designed to be economical and also produce bright lights. However, it isn’t easy to get stable materials that produce bright emissions if not economically viable.

Scientists from the CeNS (Centre for Nano and Soft Matter Sciences), an independent research organization under the Department of Science and Technology, India, found that simple plasma treatment of cesium lead halide nanocrystals can lead to increased stability of the material many folds, enabling the development of durable and bright LEDs.

The team led by Dr. Pralay K. Santra has found that plasma treatment of some inorganic nano-materials can lead to a stabilized material that gives bright and stable light emission. It may also allow for the better fabrication of covert double-layer security tags. The team has shown that plasma treatment induces stability in inorganically-derived perovskites that can enhance their emission. This is a major step towards the commercialization of such materials. Plasma induced the bonding of oxygen-containing molecules, oleylamine, on the surface of nanocrystals. This leads to more stable and brighter LEDs. Plasma treatment strengthens the bonds between the ligands present in the nanostructures, thereby enabling better encapsulation and increased PL intensity. They developed a novel method that uses the plasma treatment to create fake security tags that look like real items and that, if used correctly, will allow counterfeit products to be detected. The teams’ results are now reported in the ACS journal Applied Nano Materials. The team is now actively looking for partners to commercialize the method.

Team members have already applied for a patent for their discovery in India and are looking for partners to commercialize the technique.
