Developing Dual-Light-Emitting Films Using Egyptian Blue and a Biopolymer Matrix

What is it about?

This work describes the development of a new type of thin, flexible material that lights up in both visible and invisible (infrared) wavelengths. This material is made by blending a natural, biodegradable polymer (commonly found in food and medicine) with Egyptian blue, a pigment used in ancient art that has special light-emitting properties. By combining these materials, a film that can glow in two different colors and could be used in technologies like medical imaging, environmental sensors, and anti-counterfeiting labels has been created. Importantly, it is made using eco-friendly ingredients and simple processing, which makes it both sustainable and versatile.
