Researchers at Shiv Nadar University, led by Professor Aloke Kanjilal and scholar Bisweswar Santra, have developed a rare-earth-free composite material with significant implications for solid-state lighting, artificial intelligence, and environmental cleanup. This innovative phosphor displays exceptional dual-band photoluminescence across the visible to near-infrared spectrum, providing a cost-effective and scalable alternative to traditional rare-earth elements. The composite enhances India’s self-reliance in advanced lighting technologies and offers potential solutions for neuromorphic computing, achieving ultra-low power consumption and rapid response times. Additionally, it demonstrates photocatalytic abilities to decompose organic pollutants in wastewater and shows resilience to radiation, making it suitable for extreme conditions. This research marks a notable step towards sustainable production methods and addressing pressing global challenges in technology and environmental health.
