TLDR
In this paper, several mechanisms were proved to be responsible for the long-wave fluorescence bands: intramolecular solvent-assisted relaxation in the excited state (I and III), ground state aggregation at low temperatures (I in nonpolar solvents), excimer formation (III), and I only at high concentrations in some solvent-free solvants.About:

Charge Separation in Excited States of Decoupled Systems—TICT Compounds and Implications Regarding the Development of New Laser Dyes and the Primary Process of Vision and Photosynthesis
TL;DR: The dual fluorescence of certain aromatic systems has greatly advanced in recent years, and the accompanying large charge separation has been linked to a twisted (or small overlap) arrangement of the chromophores as mentioned in this paper.

A highly selective charge transfer fluoroionophore for Cu2
TL;DR: A dual fluorescent charge transfer fluoroionophore with its ionophore incorporated in the electron acceptor was developed and was found to show a highly selective fluorescent response to Cu2+ with a dramatic enhancement in its CT emission.

Reinterpretation of the anomalous fluorescense of p-n,n-dimethylamino-benzonitrile
TL;DR: In this paper, the existence of two excited species differing in polarity and in the orientation of the N(CH 3 ) 2 group has been attributed to the presence of an excimer.
