A breakthrough in lighting technology has been achieved by researchers at the Centre for Nano and Soft Matter Sciences (CeNS) in Bangalore. They have developed a method to improve the stability of perovskite LEDs (PeLEDs) by reducing anion migration, a key factor in color instability and sensitivity to heat and moisture. By using cesium lead bromide nanocrystals and an argon-oxygen plasma treatment, the team has created a protective barrier that prevents anion migration, making PeLEDs more durable and efficient for real-world applications.
In another development, researchers at the Indian Institute of Science (IISc) in Bangalore have made progress in designing fatigue-resistant multi-principal element alloys (MPEAs). By manipulating the chromium-nickel ratio and exploring microstructural features, the team has created single-phase and dual-phase MPEAs with enhanced cyclic strength and fatigue life. This innovative approach challenges traditional beliefs about alloy strength and fatigue performance, opening up new possibilities for structural applications.
These advancements in LED and alloy technologies showcase the potential for cost-effective and durable solutions in the field of optoelectronics and material engineering. The future looks promising for these developments as they pave the way for more efficient and reliable devices in various industries.
