Researchers at the Indian Institute of Science (IISc), Bengaluru, have developed a pioneering device that transforms infrared light into visible light. This breakthrough holds significant potential for applications in imaging, sensing, and communications technology.

The newly developed device utilizes a novel method to achieve this conversion. By employing advanced materials and innovative design, the researchers have created a system that can efficiently upconvert infrared light. It involves using a mediator material that absorbs infrared light and re-emits it as visible light, a process enhanced by nanostructures that act as optical antennas, concentrating the light and energy onto the mediator material.

This advancement is not just a scientific curiosity; it has practical implications in fields such as night vision and medical imaging. Infrared light can penetrate deeper into biological tissues compared to visible light, and converting it to visible light can enable clearer and more detailed imaging. It can be beneficial in medical diagnostics and treatments, including photodynamic therapy.

The IISc team is now focusing on improving the efficiency and scalability of their device to make it viable for commercial applications. If successful, this technology could revolutionize various industries by providing a new way to harness the advantages of infrared light for everyday use.
