Thus, two simple fluorophores can be readily combined to give emissions over much of the visible spectrum, all requiring only a single excitation.
We set aside the use of light bulbs because they give emissions in the visible and adjacent infrared parts of the electromagnetic spectrum, for which the skin is poorly absorbent and particularly reflective.
CPC gives emission peak at 465 470 nm when excited at 386 nm.
Under the given emission constraints, the deployment of both technologies reduce total system cost of electricity generation.
"Given emission standards recently introduced by the current administration, any new coal-fired plants would be far cleaner than their predecessors".
The Pareto-frontier obtained as the global solution of the optimization problem delivers the minimal CO2 emission rates, achievable with the technology considered for a given accepted investment, or respectively the minimal cost associated with a given emission abatement commitment.
There are inherent difficulties associated with climate change negotiations, ranging from which countries should bear most responsibility for a given emission reduction target to the assessment of a globally efficient time path for pricing harmful greenhouse gas emissions (GHGs).
The FS moiety was electronically excited at wavelength (λ exc) = 470 nm and gave emission bands centered at wavelength (λ emi) = 650 and 778 nm (Fig. 7a).
The SS moiety was electronically excited at wavelength (λ exc) = 470 nm and gave emission bands centered at wavelength (λ emi) = 620, 640, and 680 nm (Fig. 7b).
From a theoretical point of view [39], the relation between XRF intensity of a given emission line and the element weight concentration in the specimen can be calculated as follows.
