The nanoparticles have a core with a negative real value relative permittivity of absolute value greater than 10 in a first range of wavelengths including near UV and visible wavelengths of light, and a shell with an imaginary relative permittivity of less than 5 in the first range of ...
By combining stimulated Raman scattering and sum-frequency generation within a single laser system, indeed often within a single resonator, it is possible to achieve frequency conversion over a wide range of output wavelengths, that are useful for a number of applications. This paper reviews the co...
(NILU-UV) irradiance meter is a ground-based, multichannel, moderate bandwidth filter instrument that measures irradiances at ultraviolet (UV) and visible wavelengths with five channels in the UV (302, 312, 320, 340, and 380 nm) and one channel in the visible (400-700 nm) part of the ...
7.2 The spectrum of the sun Visible light and infrared radiation constitute the major fraction of solar radiation reaching the atmosphere of the Earth (Fig. 7-1). Approximately 40 % of the radiation energy is visible light of wavelengths between 400 and 700 nm. Ultraviolet radiation is divided...

Ultraviolet-visible (UV-Vis) spectrophotometry is arguably the most common as well as one of the oldest forms of absorption-based analysis. UV and visible regions of the electromagnetic spectrum are contiguous: UV wavelengths range from 10 to 4000 angstroms; visible wavelengths range from 4000 to ...
紫外-可见分光光度法（UV-vis spectrophotometry）Appendix IV A UV visible spectrophotometry Calibration and verification of instruments Because of the influence of environmental factors on the mechanical part of the 1. wavelength, the wavelength of the instrument often varies slightly The instrument shall ...
Various chemimechanical refiner pulps (unbleached, -bleached and pre-yellowed) were irradiated with monochromatic light at selected wavelengths. The change in reflectance at 457 and 557 nm was monitored using UV-VIS reflectance spectroscopy and post-color values were calculated from the reflectance chan...
Animal colour signals serve important functions in intraspecific interactions, including species recognition, mate choice and agonistic behaviour. An increasing interest concerns ultraviolet (UV) wavelengths, for instance studies on the effect of UV in mating decisions. More recently, some studies also est...
UV-Visible and AFM Studies of Nonionic Microemulsions The wavelengths corresponding to the maximum absorbance of the oil in microemulsions (λ) were compared to the wavelengths of the pure oil (λo). It ... M Fanun,S Makharza,M Sowwan - 《Journal of Dispersion Science & Technology》 被引...
