Under 980 nm laser exposure, the UV light emitted by the single UCNP is absorbed by the PNB inner layer, which results in cleavage of o-nitrobenzyl groups and formation of carboxylic acid groups. The increasing hydrophilicity of the diblock copolymer resulting from the NIR light-triggered ...
As UV light is unfavourable for light to energy-conversion systems, IR-light absorbers are the key to responding to this challenge. However, simultaneous pursuit of clear and colourless IR-induced carrier transfer has been an important goal of photochemistry research. The development of an IR-...
'Infrared signal intensity' refers to the amount of infrared light absorbed by bonds in a substance, such as ethanol in the case of an alcohol sensor. The change in intensity helps determine the concentration of the substance, like ethanol, being analyzed. ...
The UV–visible–NIR transmittance spectra were obtained by measuring the transmitted light intensity of an Ocean Optics HL-2000 broadband light source with a calibrated Ocean Optics Flame-T spectrometer. The transmittance of the electrodes on glass was measured using an Agilent CARY-7000 spectrophotome...
IR Lenses used to manipulate light in a variety of infrared applications such as thermal imaging, laser focusing, or FLIR are available at Edmund Optics.
An analysis is performed of selected light curves for the short-period RS CVn group: UV Psc, XY UMa, RT And, SV Cam, BH Vir, ER Vul, WY Cnc, and Cg Cyg. The photometric fitting parameters are optimized for the 'distorted' light curves in... E Budding,M Zeilik - 《Astrophysical ...

light source and detector, respectively. Transient absorption spectra were measured from 500 nm to 1 μm. The spectra were obtained at 200-nm intervals and averaged over 300 scans for a spectrum by irradiating the sample using a pumping wavelength of 1200 nm generated by UV laser pulse...
Efficient photopolymerization activated by nonharmful near-infrared (NIR) light is important for various biological applications. Here we propose a NIR light free-radical photoinitiator (PI) fabricated by incorporating oxime-ester coumarin functionality
