A new one-step process miniaturises OLEDs to smaller than their emitted wavelength, enabling precise control of light ...

Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can ...

OLEDs are also commonly referred to as organic LEDs and organic electroluminescent diodes. They operate due to the phenomenon of electroluminescence. A thin organic film is sandwiched between two ...

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 ...

Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge deposition ...

This illustration depicts the QAO family dopant integrated into the organic light-emitting diode structure. By designing a molecule with a lower HOMO level than that of the host material, the ...

A research team has successfully synthesized a new class of helical quinolizinium salts exhibiting exceptionally strong fluorescence in the orange-to-red light region (606–682 nm). Smart glasses that ...

Through experiments on animal models, the team confirmed that red light most effectively improves Alzheimer's pathological markers and memory function. The research findings were published online in ...
