The excitation-emission matrix discussed above was used to obtain the quantum yield
at any excitation wavelength relative to the quantum yield
at the reference wavelength of 490 nm.
Moreover, it led to a significant decrease in the quantum yield
of photosystem II, lower [K.
6) The reciprocal of the quantum yield
is called quantum requirement and it is often used in efficiency analysis of photosynthetic energy conversion.
The bulky pendant groups could decrease the aggregation and improve the PL quantum yield
Nevertheless, the quantum yield
for HPD photobleaching was only 55% greater in [D.

In the ideal case where every photon is detected with the same probability, the value of m should be 1 since if the quantum yield
is 1, every absorption leads to an emitted photon and the measured absorbance, [A.
Irradiated for 3 min with a 50 W high-pressure mercury lamp at 25[degrees]C, ESR intensity of BCTE-HABI system is obviously more regular and higher than that of o-Cl-HBAI system, which indicates the higher quantum yield
of triarylbiimdazolyl radicals produced respectively.
6, 2014 /PRNewswire/ -- Quantum Materials Corp(OTCQB:QTMM) (QMC) today announced achieving a calculated 95% Quantum Yield
(QY) for Green Tetrapod Quantum Dots(TQD) manufactured by QMC's proprietary automated mass-production system.
Several previous papers from our group discussed the measurement of fluorescent quantum yield
(QY), and light scattering and absorption cross sections using a spectrophotometer with an integrating sphere detector (1), (2).
are also affected by the amount of the dye molecules in each nanoparticle and the size of the nanoparticles.
The synthesized polyimides emit blue to green light with a quantum yield
