quantum yield in a sentence

Examples

1. The heavy atom effect also held for the Y-Tex, In-Tex and Lu-Tex triplet quantum yields and lifetimes.
2. These solar cells are only activated in the UV region and result in a relatively high quantum yield of 16 % electron / photon.
3. In contrast, the paramagnetic metallo-texaphyrins, Mn-Tex, Sm-Tex and Eu-Tex, have undetectable triplet quantum yields.
4. Foscan has a singlet oxygen quantum yield comparable to other chlorin photosensitisers but lower drug and light doses ( approximately 100 times more photoactive than Photofrin ).
5. In optical spectroscopy, the quantum yield is the probability that a given quantum state is formed from the system initially prepared in some other quantum state.
6. A corollary of Kasha's rule is the Vavilov rule, which states that the quantum yield of luminescence is generally independent of the excitation wavelength.
7. Photosensitiser ZnPcS 4 has a singlet oxygen quantum yield of 0.70; nearly twice that of most other mPCs ( ?? at least 0.40 ).
8. For example, a triplet transition quantum yield is the fraction of molecules that, after being photoexcited into a singlet state, cross over to the triplet state.
9. It has been found, however, that the chemiluminescence intensity corrected for quantum yield decreases as the singlet excitation energy of the fluorescent molecule increases [ 6 ].
10. Quantum yields greater than 1 are possible for photo-induced or radiation-induced chain reactions, in which a single photon may trigger a long chain of transformations.
