Researchers at the National Institute of Technology Rourkela (NIT Rourkela), in collaboration with IIT Guwahati, IIT Bombay and NISER Bhubaneswar, have developed lead-free light-emitting materials that respond to heat and moisture, opening up potential applications in anti-counterfeiting, humidity sensors and lighting technologies. The bismuth-based materials can change their light-emission properties in response to environmental conditions, […]
