Incandescent and luminescent light
Did you know?
Luminescence is the "spontaneous emission of radiation from an electronically excited species (or from a vibrationally excited species) not in thermal equilibrium with its environment", according to IUPAC definition. A luminescent object is emitting "cold light", in contrast to "incandescence", where an object only emits light after heating. Generally, emission of light is due to the movem… WebThis recycling of infrared light pushed the device’s efficiency to 25.4 per cent – that is on par with common LEDs, but more than a tenfold improvement over conventional lightbulbs.
