Scientists from the Nanoscience and Technology Department at the University of Calicut have developed new devices based on the Golden Hill alloy, which is a breakthrough progress in the diode technology (LEDs) emitting the next generation.
Es Shibu, Associate Professor in the Smart Materials Lab Lab, and rival Jose, his PhD student, is behind the initiative. They argue that although these clusters are invisible to the naked eye, they show exceptional photophysical properties, including strong light emissions, excellent photography and thermal stability and environmental compatibility. Thanks to these features, they are ideal for future applications in sustainable lighting, display and biomedical display.
According to Mr. Shibu and Mr. Jose, this innovation distinguishes its production method-by-Simpled process based on a solution that is environmentally friendly that avoids the use of toxic or expensive host materials. As a result, technology is both sustainable and cost -effective. The core of the invention consists of atomically accurate nanoclastres made of only a few metal atoms, they say.
The newly developed LED based on nanocluster emits pure red light and achieves an external quantum efficiency of 12.6%. Mr. Shibu says this is one of the highest performances recorded in the Nanocluster, unprocessed LED LED with saturated red emission.
Their findings were published in Advanced Materials (Wiley), one of the most prestigious magazines in the field of material science, with an impressive factor in the impact of 27.4. This also represents the first publication from the University of Calicut in such a high impact magazine.
Success was made possible through national and international cooperation with institutions such as the Indian Institute of Science, Bengaluru, the Indian Institute of Technology, Madras, Tampere University, Finland and Hokkaido University in Japan. Research was primarily supported by financing from the Ministry of Science and Technology-Propagation of University Research and Scientific Excellence, with further support of science and engineering research council of research grant, Kerala State Council for Science, Technology and Environment Science Scheme and Japanese Society for Promotion.
