Contact and Distant Luminescence Quenching in Solutions
Figure 15
The field dependence of the MFE at contact start in
the exact theory (solid line) and in the elementary spin model (dashed-dotted
parabolic line). The vertical line separates the low field (incoherent) -dependence from the high field MFE,
originating from the coherent spin conversion. The latter is well interpolated
by the empirical formula shown as the dashed curve approaching the exact result
from above. The highest field asymptotic behavior and its limit, ,
are shown by the dotted lines below. The rate of contact recombination, ,
and other parameters are the same as in the previous figure while .
