The increase in the electrical conductivity of the saline solutions used in the irrigation of the plants negatively affected the
quantum efficiency of photosystem II and the electron flow per reaction center, thus modifying the emission of chlorophyll a fluorescence, implying severe damage to the photosynthetic apparatus of the sorghum plants.
where [[lambda].sup.4.sub.peak]/8[pi][cn.sup.2] can be regarded as a constant and [eta] is the
quantum efficiency. The calculated results have been shown in Table 1 and Figure 5.

quantum efficiency," Solar Energy Materials and Solar Cells, vol.
With regard to this issue, we developed a photon detection system that has high
quantum efficiency (988%) and is able to discriminate the number of incident photons.
(b) Normalized fluorescence enhancement (blue) and modified
quantum efficiency (green) of a single emitter with intrinsic
quantum efficiency 0.3.
It is noted that our LED devices which are fabricated using the above InGaN/GaN MQW structure show an external
quantum efficiency of up to 24.2% (light output power of 13.31 mW at 20 mA current injection).

quantum efficiency green InGaN light-emitting diodes with large overlap quantum wells," Optics Express, vol.
In this case, one calculates the
quantum efficiency of energy transfer:
The X-ray detector possesses known active silicon thicknesses and 100 percent internal
quantum efficiency, making possible absolute measurement of X-ray flux with energies 100 keV and beyond.
