Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing ...

Now researchers in Japan have reported the world’s first continuous-wave UV-B semiconductor laser diode operating at room temperature on a low-cost sapphire substrate. This breakthrough by researchers ...

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 ...

A new diode looks set to steal the humble LED's thunder. Dubbed a diode for light, and crafted using standard silicon chip fabrication techniques, this is a key discovery that will pave the path to ...

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 ...

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 ...

Light can be produced and/or controlled electronically in a number of ways. Among the widely used of all the different types of semiconductor diodes are the Light Emitting Diodes or LEDs. It is a PN ...

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 ...
