I want adequate funding for education in Australia and the ministers will all take a view it's about increasing the quantum of funding, not shuffling the deckchairs".
Mediated electron transfer with benzophenone or xanthone tethered to the picolinium moiety in the presence of a photosensitizer was used to increase the quantum yield of carboxylic or amino acids release to Φ = 0.72 at λ = 380 (Scheme 118).
Comparing with the free-space radiation, the increase in the radiative rate would directly increase the quantum yield and decrease the lifetime of a fluorophore.
Doping nitrogen atoms could increase the quantum capacitance and overcome the limitations of total capacitance at PZC.
Using steady-state and time-resolved fluorescence techniques, we demonstrated that TPPS4 stimulated disaggregation of aged CdSe/ZnS-Cys QD in aqueous solutions, increasing the quantum yield of their luminescence, which finally reached that of the fresh-prepared QD.
Increasing the quantum yield of the gain media will depend on the degree of the overlap between the LSPR spectra and the emission of the RhB.
Another advantageous function of Au/TiO2 nanocomposites is that Au nanoparticles work as electron storage, effectively reducing the recombination of photoexcited electron-hole pairs, and eventually increasing the quantum yield of photocatalysis [17, 18].
As hypothesized, introduction of the phenyl spacer in the C8 position increased the quantum yield of 31 to a satisfactory 67%% (Table 1).
This Review summarizes results from the physics literature which demonstrate the effects of metallic surfaces, colloids, or islands on increasing or decreasing emissive rates, increasing the quantum yields of low quantum yield chromophores, decreasing the lifetimes, and directing the typically isotropic emission in specific directions.
This change increased the quantum yield of the probes in the Zn2+-free state such that they no longer exhibit a fluorescent response to Zn2+ binding.
