There is a blue shift in the absorbance of indole and phenol upon increasing solvent polarity. As a result, there will often be a blue shift in the absorbance of tryptophan (typically monitored as a decrease in absorbance in the 291- to 294-nm region of the spectrum) or tyrosine (at ...
It was found that a huge 68.4 meV blue shift in electroluminescence (EL) peak position as the injection current is increased from 3 to 50 mA for the MQD LED. The large EL blue shift reveals that deep localization of exitons (or carriers) originates from QDs will strengthen the band-...
Strain engineering has been shown to induce shifts in the band structure of semiconductors. In this work, we demonstrate a blue shift in the band gap of GaAs micropillars of greater than 50meV using SiNx. GaAs micropillars were fabricated and conformally coated with highly strained SiNx. The ...
The peak at 254 cm-1 undergoes a 2-cm-1 shift to lower energy in D2O and is assigned to a Cu-imidazole vibration of the histidine ligand. All of the resonance-enhanced modes display narrow excitation profiles which maximize at 600 nm (at 15 and 90 K) and appear to coincide with one...
BV binds to Cys253 in the GAF domain in two ways, either via the C31 atom or via the C32 atom in an approximate 1:1 stoichiometry (Fig. 1). The unique chromophore species that result from this binding appear to be responsible for the spectral blue shift and the high fluorescence ...
To probe this hypothesis and test whether NobZIP77 directly interacts with the promoter ofNoDGAT2B(pNoDGAT2B; and of additional predicted target genes or PTGs), electrophoretic mobility shift assays (EMSAs) were used to identify specific band shifts of ACGT-harboring promoter probes (the binding...
Relatively large bandwidths of both absorption and resonance Raman spectra have been observed in supercritical solvents compared with those in liquid solvents of a similar absorption peak shift. We interpreted this as due to the small refractive indices of the supercritical solvents relative to the ...
While in disordered cuprorivaite all Raman bands broaden, the most pronounced band shift occurs in the case of the Si–Obridge–Si stretch vibrational mode between approx. 1081 cm−1(lowest crystallinity) and 1088 cm−1(highest crystallinity) (see Figs.S32a,S33a). Such large band shift ...
1) blue-shift of optical band gap 光学带隙蓝移2) bandgap blue shift 带隙蓝移 1. The result shows that the bandgap blue shift depends on the thickness of quantum wells and the depth of quantum well layer which forms the surface. 研究结果表明 ,由氖离子注入引起量子阱带隙蓝移 。
