Abstract
Lead sulfide QDs of ∼4.5 nm in size embedded in glass and colloid matrices have been studied using picosecond pump-probe differential absorption and luminescence techniques. Energy and temporal characteristics of charge carriers relaxation processes by direct electron-hole recombination and through deep surface defect states are evaluated. An influence of type of matrix on the defect structure and relaxation rate is discussed.
