These LEDs use advanced intercalation techniques to maintain brightness and minimize energy loss, opening doors to more ...

These are a blue LED with yellow phosphors ... Recent research has heavily focused on improving the external quantum efficiency (EQE), which is commonly defined as the product of the injection ...

The resulting LED devices achieve a maximum external quantum efficiency of 19.1%, a brightness of more than 40,000 cd m-2, and an operational lifetime of more than 232 h (T 50 @100 cd m-2). Meanwhile, ...

Light-emitting diodes (LEDs), semiconductor-based devices that emit light when an electric current flows through them, are ...
