Bloch surface wavesBiomolecule detectionPlasmonicsWe designed a Bragg mirror structure with an SiO2 top layer to create a resonance in the ultraviolet wavelength range, near the absorption peak position of various proteins. We demonstrate that the wavelength of enhanced sensitivity can be adjusted by ...
The longer the wavelength, the less energetic the radiation. The near ultraviolet, abbreviated NUV, is the light closest to optical or visible light, and covers a wavelength range between 300 and 400 nm. The far ultraviolet, abbreviated FUV, lies between the near and extreme ultraviolet regions...
Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It is so named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet (purple). ...
Definition A form of ELECTROMAGNETIC RADIATION, shorter in wavelength than visible light. Ultraviolet wavelengths range between about 1 nm and 400 nm. Ordinary glasses are not transparent to these waves; quartz is a much more effective material for making lenses and prisms for use with ultraviolet....
The majority of light emitting bio-labels are excited in the ultraviolet (UV) to visible wavelength range (∼300–∼700 nm) [31], [32], [33]. Therefore, to support this rapidly emerging field, there is a growing effort to develop complementary integrated sources. This review will ...
Ultraviolet ( UV ) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, that is, in the range between 100nm to 400nm. It is so-named because the spectrum consists of electromagnetic waves with frequencies higher than those that ...
Ultraviolet waves are just shorter than the violet end (shortest wavelength) of the visible light spectrum. This branch of astronomy has provided additional information about stars (including the Sun), galaxies, the solar system, the interstellar medium (the "empty" space between celestial bodies),...
aSpectrograph drift measurement based on the Fabry-Pérot (FP) etalon in the visible (VIS) wavelength and the laser frequency comb (LFC) in VIS and ultraviolet (UV) wavelength range. The FP calibration data has been restricted to its spectral overlap with the VIS LFC; Error bars indicate for...
Examples are the nucleobases (adenine, cytosine, guanine, thymine, and uracil) and their multimers up to the double-stranded DNA helix, as well as the aromatic amino acids (tryptophan, phenylalanine, and tyrosine), all of which have strong absorption bands in the 250–300 nm wavelength range ...
[81,82] focused on X-ray spectra, which were obtained with little or no spatial resolution and required scans across the wavelength range, while the detection of transient ionisation from EUV was hampered by the twin problems of slit and throughput/cadence. For the first time, SISA will ...
