An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...
Organic Light Emitting Diodes (OLEDs) have gained significant attention since researchers at Eastman Kodak pioneered the development of OLED technology in the 1970s and demonstrated the first ...
The direct band gap of AlN-based materials makes them suitable for fabricating DUV optoelectronic devices, which have a wide range of application prospects in the fields of curing, water and air ...
