Engineers in Switzerland have built light-emitting diodes so small that hundreds could line up across the width of a single human cell, shrinking a core component of modern electronics to a scale that ...

Living bacteria embedded in silicone can absorb green LED light and re-emit it as red, offering a potential sustainable ...

Researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses. Nagoya ...

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 ...

What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

A naked flame is a complex soup of ionised gases, that possesses an unexpected property. As you might expect with that much ionisation there is some level of electrical conductivity, but the unusual ...

Nagoya University scientists, in cooperation with Asahi Kasei Corporation, have succeeded in designing a laser diode that emits deep-ultraviolet light, according to research published in the journal ...
