quenching.” Concentration quenching is proposed to take place by successive
energy transfer (F¨rster type) and trapping at a lower energy site that can be a
nonradiative channel for the excited state [
46
]. The trap is often a special molecular
nonemissive aggregate, in which the molecules are close enough to interact,
resulting in quenching of emission [
47
]. The behavior of solid-state AIEE on the
basis of conformational distortion, restriction, or immobilization in the nanoparti-
cles shed light not only on a new light harvesting system but also on a new
fluorescent probe in concentrated conditions. In any case, I anticipate that future
improvements in organic dye nanoparticles will provide increased benefit to areas
of life as well as material sciences.
