Notes:
We report on picosecond dynamics of photoexcited carriers in CsPbCl3 nanocrystals in a CsCl host. For low carrier densities, photoexcited carriers form excitons, which decay with a characteristic time constant of 170 ps at 300 K. Under strong photoexcitation, we have observed the Auger recombination with the Auger coefficient C(approximate)10−29 cm6 s−1. We have identified the onset of the Auger recombination at the carrier densities of (approximate)1020 cm−3 as the Mott-like transition from excitons to electron–hole plasma in nanocrystals. © 2000 American Institute of Physics.
