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
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.
