Uversky and Fink reported such proportionality behavior at a different wavelength for intermediate states of a variety of proteins (23).
This is accomplished by a sequence of optical pulses: first an intense radiation pulse that creates an excited singlet state and, after a delay, a second, weaker pulse at a different wavelength, or range of wavelengths, that probes the transient absorption.
In the present case, the UV emission is observed at a different wavelength compared with most of the reported values for ZnO nanostructures [20].
Fluorescence is the emission of light by a substance following absorption of light or other electromagnetic radiation of a different wavelength.
In each group, the filters are composed by 11 layers of TiO2 and SiO2, and can be easily tuned to a different wavelength by adjusting the thickness of the resonance cavity, e.g., the 6th layer (Table 2 > >).
Excitation of the fluorophore by polarised light enables it to emit polarised light of a different wavelength, but if the molecule is tumbling free in solution the emitted light radiates in different directions and the light signal is scrambled rather than polarised.
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation of a different wavelength.
If the activation density is lower than optimal, image acquisition can be accelerated by applying auxiliary activation light of a different wavelength.
Different pigments reflect different wavelength of the light that is characteristic of its color.
The device could take photographs of a painting at different wavelengths of light, from infrared to ultraviolet, allowing him to distinguish, without damaging the work, the kind of pigments an artist had used.
