Photoluminescence up-conversion involving surface states in colloidal CdTe quantum dots

Not Accessible

Your library or personal account may give you access

Abstract

Efficient photoluminescence up-conversion was observed in colloidal CdTe quantum dots with an energy gain of ~360 meV. We attribute this up-converted signal to the recombination of carriers from conduction band and hole surface states, respectively.
