As it is shown in Figure 4, on paper with a minimum content of OBAs, the luminescence peak is in the short area of visible spectrum
([lambda] = 430-440 nm), partly caused by paper luminescence, partly by luminescence of PVP in ink compositions and luminescence of ZnO/Si[O.sub.2] nanoparticles in this area of visible spectrum
(see Figure 1).
Unfortunately, the eye's response to the wavelengths transmitted by this dense filter (only 3% of the visible spectrum
) is feeble because your retina's cone cells are comparatively insensitive to blue and violet light.
Sunlight is made up of different wavelengths of colors; the visible spectrum
is the wavelength most absorbed by the solar cells.
The visible spectrum
spans from about 400 nanometers for violet to 700 nanometers for red.
The top row consists of light emitting diodes (LED's) which in reverse bias mode, offer the feature that an LED will be receptive to wavelengths of light, less than their own peak wavelength and covering that area of the visible spectrum
of [lambda] = 520 nm to 400 nm with some incursion into the ultraviolet region of the spectrum to as low as 200 nm.
However, to the best of our knowledge, few studies examine the use of cosensitization to broaden the light absorption spectra of N719 in the blue part of the visible spectrum
. In this work, we report a new triazoloisoquinoline-based dyestuff, which can be used in a cosensitized dyestuff to absorb the blue part of the visible spectrum
What name is given to an optical device which splits white light into the visible spectrum
This instrument is programmed to take absorbance readings of a single sample at different wavelengths or over a specific period of time, and allows high-speed wavelength scanning across the UV and visible spectrum
. The instrument is also equipped with RFID technology, which not only helps operators track their samples, but also helps them manage their labs.
It is well known that nanostructures constructed using metallic particles are capable of supporting surface plasmon modes with resonance frequencies in the visible spectrum
MSX adds the detail of real-time visible spectrum
images captured by the built-in digital camera to thermal spectrum images, providing extraordinary sharpness, contrast and clarity previously unavailable in thermal imaging, www.FLIP.com.
Coat'N'Cool is an architectural coating specially engineered to reflect sun light in the UV, IR and visible spectrum
. It was engineered through the use of waterborne epoxy technology and complex inorganic compounded pigments (CICP's).
The 34 detection channels in the LSM 780 can acquire full spectral information across the entire visible spectrum
; and through the use of reference spectra of each of the individual fluorescent proteins, linear unmixing can be used to clearly separate the different proteins into distinct channels.
