QDs are small, bright, photo - stable materials that possess nanosecond fluorescence lifetimes.
Besides, there are orders of magnitude more elastic collisions than inelastic, so in fact the lifetime of an excited CO2 molecule before an inelastic collision is much longer than the one nanosecond average time between elastic collision.
The time interval between molecular colliwsions is a few nanoseconds; but the lifetimes of the excited states, can be microseconds to milliseconds; so the energy is lost in collisions, before the molecule gets a chance to re-radiate.
