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 light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Appearing as practical electronic ...

A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited ...

A major street light upgrade programme will be good for the environment and save nearly £1m every year in energy bills, ...

LED, or light emitting diode therapy, is a skincare treatment that uses varying wavelengths of light, including red and blue. NASA originally developed it for plant growth experiments on shuttle ...

Scientists have developed the tiniest pixel ever made – just 300 × 300 nanometers – and it's bright enough to rival today's ...

At-home LED devices, particularly those that combine red and blue light, are efficacious for acne and can likely complement other over-the-counter and prescription treatments. HealthDay News — At-home ...
