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 ...
Colloidal quantum dots (QDs) exhibit exceptional properties of narrow-band emission, tunable luminescent wavelength, high luminous efficiency, and remarkable material stability across the visible and ...
Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...
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 ...
Stanley Electric has patented a semiconductor light emitting device that emits mixed color light using a semiconductor light emitting element and a fluorescent body layer containing specific ...
A new one-step process miniaturises OLEDs to smaller than their emitted wavelength, enabling precise control of light direction and polarisation for displays, sensors and optical uses. (Nanowerk News) ...
A team of interdisciplinary scientists has developed flexible fibers with self-healing, light-emitting and magnetic properties. The Scalable Hydrogel-clad Ionotronic Nickel-core Electroluminescent ...
