Durham University researchers discover new ways to control light emission in advanced materials
Scientists at Durham University published two papers in Nature Communications describing molecules that glow for over twelve seconds and exhibit unusual energy arrangements.
Molecules produce long lasting blue light
Ph.D. student Carolina Francener and professor Andrew Monkman directed research into a substance named monohomotruxene. This specially designed compound made of carbon and hydrogen produces a cyan-blue glow visible for more than twelve seconds after the light source switches off. The study found that changing the molecule's shape influences brightness, color, and duration without needing heavy metals. These findings could help develop materials for security printing and specialist optical technologies.
Second study shows unusual energy levels
A second paper by Monike da Silva Kutz examined a molecule known as HzTFEX2 under low-temperature conditions. The team found experimental evidence supporting an unusual arrangement of energy inside the molecule that defies normal expectations. They discovered how the molecule responds depends on light exposure and its surrounding environment. This study offers fresh understanding of the way molecules take in, move, and give off energy.
Future applications for displays and security
Both studies demonstrate how understanding molecular structure helps scientists control light emission in future materials. Although further research is needed before developing practical products, the discoveries provide an important foundation for advances. The papers were published in Nature Communications in 2026 with specific DOI numbers provided by Durham University.
