A method to increase the efficiency of light-emitting materials is receiving a lot of attention.
A research team led by Lee Min-hyung, a professor at the Department of Chemistry at the University of Ulsan, announced on June 23 that it has successfully developed a technique that can improve the efficiency of light-emitting materials used to make organic light-emitting diodes (OLED) by more than 30 times. OLED is utilized to produce displays for TVs or smartphones.
The research team was able to drastically increase light-emitting efficiency by making the molecular structure of light-emitting materials stronger using a method to synthesize molecules. They discovered that the result was attributable to a change in the molecular structure in an excited state generated by light.
Professor Lee explained, “The newly-developed technology has increased our understanding about the light-emitting mechanism of light-emitting materials, and can maximize light-emitting efficiency while minimizing power consumption as well. So, I think that it will contribute hugely to improving the function of electronics like OLED TVs or smartphones.”
The research findings were first published online on June 15 by the Journal of the American Chemical Society, a weekly scientific journal published by the American Chemical Society.
