Considering the molecular complex, we can discuss photoluminescence dynamics with energy level argument. There, triplet states have longer decay constant comparing with singlet one. We can design molecules considering heavy-atom effect to use triplet states or sth. Then, my question is what determines the lifetime of semiconductors? For example, don't we need to consider heavy-atom effect in CsPbBr3? Then what should we consider such hybrid-semiconductors?
