Incandescent and luminescent light
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… WebApr 12, 2024 · The glowing filament radiated both visible and infrared light. The quartz slab was made up of extremely thin layers of the mineral, designed in a way that redirected the infrared radiation back to the filament. ... “The efficiency of the device is impressive, but this is a much more complex device than a traditional incandescent light bulb.
