William S.Hanson, inEncyclopedia of Archaeology, 2008 Future Developments Visible light represents only one range of wavelengths within the electromagnetic spectrum. The archaeological potential of other wavelengths, such as in the near infrared or thermal ranges, is still undergoing assessment, but it ...
In this work design, simulation and fabrication of three thin-layer optical filter based on 1D Photonic Crystals (PhCs) has been proposed. Each filter is suitable for a specific area of visible spectrum such as blue, green and red respectively. Each of three filters is placed on top of an...
It flew with the ATLAS I mission in March 1992. This paper is dedicated to the visible part of the solar spectrum. Comparisons with recent data are shown and differences below 450 nm are discussed.doi:10.1007/978-94-011-5000-2_4Gérard Thuillier...
Light is not the only type of electromagnetic radiation—it is, in fact, only a small segment of the total electromagnetic spectrum—but it is the one form the eye can perceive. Wavelengths of light range from about 400 nm at thevioletend of thespectrumto 700 nm at theredend (seetable)...
Across all skin tones and differences in pigmentation, human skin is dominated in the long-wavelength range (590–660 nm) (Fig.2a)25, but it is unclear which bands in the human skin spectrum are most attractive toAe. aegyptimosquitoes. To examine whetherAe. aegyptiexhibit different preferenc...
35. They also demonstrate highly efficient and tunable emission with high colour saturation across the visible spectrum under X-ray or visible-light irradiation. Furthermore, Sn-based perovskite nanocrystals can have optical bandgaps that extend into the near-infrared light region36,37. A fundamental...
The vacuum ultraviolet (VUV) spectrum of GdF3:Eu3+ NCs shows that the Gd3+ ion can absorb one VUV photon excited in the 6GJ levels and relaxes through two-step energy transfer to Eu3+, yielding two visible photons at room temperature. The visible quantum efficiency of GdF3:Eu3+ NCs ...
We demonstrate significant photoresponsivity in aqueous media to visible light of pseudo-oligonucleotides possessing 4-(dimethylamino)azobenzene (4-DMAzo) side chains. The spectrum of the 4-DMAzo moiety during 436 nm light irradiation at pH >9 was clearly different from that of the all (E)-form...

in MIR range, Fourier transform infrared spectroscopy (FTIR) was performed on a Ta2NiS5sample on CaF2substrate to obtain the reflection spectra from 2.5 μm to 16 μm (Fig.1c). A genetic algorithm41was used for fitting the reflection spectrum (Supplementary Note3). The fitted ...
