They just absorb blue light, transform it, and
re-emit it as a different bright color, most as red, orange, or green.
The team from the US Department of Energy's Lawrence Berkeley National Laboratory coated tiny particles with an organic dye, which greatly enhances their ability to capture near-infrared light and
re-emit it as visible light.
It is deemed rare for amphibians like frogs to exhibit fluorescence, the ability for something to absorb light at short wavelengths and
re-emit it in a longer period of time.
Some dark pigments stay just as cool as white thanks to fluorescence, which occurs when fluorescent materials immediately
re-emit absorbed light.
In an LSC, luminescent species absorb the solar radiation which then
re-emit the light at a longer wavelength.
Second, certain sorptive-based IPPT may
re-emit captured VOCs upon saturation and subsequently become a source of indoor pollution themselves.
The object will also
re-emit the same 80 units into the cavity.
Various fluorophore compounds absorb light of a specific wavelength and
re-emit light at longer wavelengths.
These agents absorb light in the ultraviolet region of the spectrum and
re-emit light in the blue region, thus increasing the intensity of short-wavelength light, which may be perceived by deer against an otherwise darker background."
In recent years, the research team has discovered that many fishes absorb the remaining blue light and
re-emit it in neon greens, reds, and oranges.
This behavior is very similar to that of optical brighteners, which absorb UV light and
re-emit it at the blue end of the visible spectrum.
