In contrast, activities of UV/Fe(III) in the presence of Mal were significantly diminished because Fe(III)–Mal complexes, with much lower quantum yield of Fe(II) from photoreduction, dominated Fe(III) speciation.
Despite the much lower quantum yield of the red tracer requiring much higher laser power, BODIPY589-GlcCer showed absolutely no bleed-through in the green channel (Fig. 3b).
Furthermore, CeF3: Eu3+/SBA-15/IS (η = 4.61%) exhibits much lower emission quantum efficiency than CeF3: Eu3+/SBA-15/SS (η = 22.77%), which indicates that the deposition of CeF3: Eu3+ onto the mesoporous framework of SBA-15 using in situ method has greatly influenced the luminescence of Eu3+ ion in CeF3: Eu3+.
> -wrap-foot> Since pH-induced spectral shifts are small (<5 nm in all cases), maxima are reported for acidic media only As expected, all the indicators possess much lower fluorescence quantum yields in the basic form compared with the acidic form (Table 1).
The first experimental studies of electrical transport in atomic carbon chains have shown a much lower conductivity than the quantum conductance limit.
The two methyl groups on the boron of 4 b are involved in the HOMO-1, but in contrast to the diphenyl substitution on 4 a, the dimethyl substitution has a much lower impact on the quantum yield of 4 b (see above, Table 1), which has a value almost eight times that of 4 a.
Luminescence spectroscopy, offering much lower detection limits, presents a quantum yield weighted average; as a consequence, the response of the observed luminescence to anion concentrations varies between solvents.
However, the delayed fluorescence depends heavily on the depositing conditions and the quantum efficiency is usually much lower than 100%%.
The fluorescence quantum yield of HSA-bound PBV is much lower than that of other fluorescent dyes used in preclinical imaging, such as cyanine dyes Cy5.5 and Cy7 having quantum yields of 0.24 and 0.28, respectively [ 35].
In metabolically active brain tissue, however, NADPH is widely believed to contribute minimally to the fluorescence signal, due to its much lower concentration in brain tissue [ 26, 27], low quantum yield [ 28], and insensitivity to metabolic perturbation [ 13, 19, 29].
Even after having been passivated with PEG2000 which is widely accepted as an efficient way to improve the quantum yield of C-dots [8], the quantum yield of C-dots is 4.33%, still much lower than that of the RNase A@C-dots.
