| 21. | Although this method provides narrow size distributions and good crystallinity, the quantum yields are ~ 5 15 %.
|
| 22. | Charge carrier trapping on QDs increases the probability of non-radiative recombination, which reduces the fluorescence quantum yield.
|
| 23. | Alkylamines have been incorporated into the TOP / TOPO synthetic method to increase the quantum yields to ~ 50 %.
|
| 24. | This is the case when measuring the quantum yield or when finding the wavelength with the highest emission intensity for instance.
|
| 25. | Since silicon is an indirect band gap semiconductor, the quantum yield of radiative recombination in this material is very low.
|
| 26. | The quantum yield for an ideal system undergoing photocatalytic events is measured as the number of events occurring per photon absorbed.
|
| 27. | The maximum fluorescence quantum yield is 1.0 ( 100 % ); each photon absorbed results in a photon emitted.
|
| 28. | Platinum and palladium derivatives have been synthesised with singlet oxygen quantum yields of 0.59 and 0.54, respectively.
|
| 29. | 2010-AIST reports a quantum yield of 19 % in photocatalytic water splitting with a caesium-enhanced tungsten oxide photocatalyst.
|
| 30. | To improve fluorescence quantum yield, quantum dots can be made with " shells " of a larger bandgap semiconductor material around them.
