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 ...

Think about how easily you recognize a friend in a dimly lit room. Your eyes capture light, while your brain filters out ...

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 ...

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 ...

The organic light-emitting diode (OLED) technology behind flexible cell phones, curved monitors, and televisions could one day be used to make on-skin sensors that show changes in temperature, blood ...

Last August, the town of Irondequoit, N.Y., near Rochester, opened its $13 million, 37,800-sf public library. The entry lobby is illuminated by organic light-emitting diode (OLED) fixtures, one of the ...

An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

LONDON--(BUSINESS WIRE)--The new light-emitting diode traffic signs and signals market research from Technavio indicates Negative growth in the short term as the business impact of COVID-19 spreads.

LEDs are capable of replacing HPS for supplemental lighting for cut gerbera production during darker periods. In Canada, as in other higher latitudes, there is not enough natural light for production ...
