Is there an actual distinction between through-space charge transfer and excimer emission?
The excimer / exciplex ground state is wholly repulsive, molecules $\ce{M  and M^*}$ diffuse together to form excimer $\ce{MM^*}$ the excimer or exciplex if formed from different species. The complex does not exist in the ground state. Emission is observed from both $M^*$ and $MM^*$. ($MM^*$ can also diffuse apart before fluorescence) The reason the excimer/exciplex emission is broad and structureless is because the ground state is repulsive. The exciplex is formed from different species so there has to be some charge transfer character, i.e. potential energy is sensitive to solvent polarity. Intramolecular excimers and exciplexes were first synthesised and studied in the late 1970's.
CT complexes are intimate in the ground state (via $\pi$ stacking etc.) and the CT absorption is generated upon absorption $(DA) + hv\to (D^+A^-)$. Any emission is then from this CT state plus normal fluorescence from either D* or A* should they be isolated in solution (as DA is in equilibrium with D and A) and then excited.
