She added: 'Our detector can offer similar performance to InGaAs in the near and shortware infrared region, and we outperform InGaAs in the visible region.'
The electronic spectra of phthalocyanines exhibit two strong absorption regions, one of them is in the UV region, and the other one is in the visible region. Also, the newly synthesized metallophthalocyanines 1a and 1b showed typical electronic spectra with two strong absorption regions, one of them in UV region between 331 and 352 nm (B band) and the other in the visible region between 674 and 682 nm (Q band) in DMSO, respectively.
(6) Colorless and transparent objects absorb wavelengths outside of the visible region, thus their light reflection is not recognizable as any color by our eyes.
0n the other hand, when the reaction was conducted under visible radiation, the Ti[(OH).sub.4] was much more active than the other catalysts, which was expected since it has a higher absorption in the visible region compared to the other catalysts (Figure 7(b)).
Generally, changes of leaf reflectance in the visible region (350-700 nm) and near-infrared region (700-1000 nm) of the electromagnetic spectrum are indication of vegetation stress [26].
Al-MCM-41@0.1Ag/Ti[O.sub.2] and Al-MCM-41@0.15Ag/Ti[O.sub.2] containing a high amount of Ag nanoparticles showed a light absorption band in the visible region with peaks at about 435 nm.
The transmittance of the ITO thin films is not a function of the oxygen flow rate, but all samples are over 85% in the visible region. At oxygen flow rate of 30 sccm, the transmittance of the ITO thin films has a maximum value of 88.7% for the wavelength of 500 nm.
This relation, also known as the Frohlich condition, is fulfilled in the near UV for a Bi nanosphere in the usual embedding media such as Si[O.sub.2] or [Al.sub.2][O.sub.3] and can be approached in the visible region upon increasing [[epsilon].sub.m] [63].
coli samples showed that the most profound inhibitory effects on E.coli amongst every applied radiation in the visible region were that of 538nm Visible Range Radiation (Green) which proved to be bactericidal.
For the ZnO film the percentage of transmittance in the visible region (390-800 nm) is about 80-87 % with a gradual fall near the fundamental absorption at 380 nm denotes the absorption edge occurs in the UV region.
The proposal of the vegetation indices more cited in literature, such as normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI), is founded on the antagonistic reflectance response exhibited by vegetation in visible and near-infrared spectral regions; i.e., accumulation of biomass leads to decreased reflectance in the visible region and increased reflectance in the near-infrared region (JENSEN, 2009).
