Exciting times for efficient, heavy-atom-free OLEDs – Phys.org

Organic light-emitting diode (OLED) displays are now very popular features of many mainstream products including smartphones and televisions. OLEDs have the advantages of being low cost, light, flexible, and easy to modify, making them ideal display materials. However, current OLEDs that achieve commercially viable quantum efficiencies contain rare metal atoms such as iridium and platinum that increase costs and reduce sustainability. Now, an international team including researchers from Osaka University…
