1.Under optical excitation only singlet exciton exists.
2.Compared to photoluminescence from dilute solution of a pure organic material, the photoluminescence from the solid state of this pure material decreases dramatically with very large redshift.This is due to exciplex formation.
3.Dimer is formed by two same molecules
4.Excimer is formed by two different molecules
5.Electric field generally assists the dissociation of exciplex.
6.There is no ground state for excimer, but exists ground state for exciplex.
7.Compared to monomer emission, the excimer emission is redshift, structureless, but short lifetime.
8.Dipole allowed optical transition occurs between two electronic state with same symmetry
9.In spectra of optical absorption or emission, the rotational energy some time is observable as fine structure
10.According to Franck-Condon principle, and if the environmental influence to the two states is small, the absorption and the emission spectra will be mirror symmetry
