Infrared Emitting PbSe Quantum Dots for Telecommunications-Window Applications

Spontaneous emission of near-infrared quantum dots controlled with photonic crystals

“…This efficiency is a lower bound as the non-radiative decay rate is overestimated. The value is in good agreement with literature [68,101,111,129,136,143,144]. A more elaborate analysis requires a detailed study on quantum efficiencies of ensembles that exhibit non-exponential decay as in Reference [226].…”

“…(b) (a) 3 nm For PbSe dots quantum efficiencies have been reported ranging from η = 12 % to η = 89 % [68,101,111,129,136,143,144]. η may change if the quantum dots are placed in a different environment, as different environments may entail different non-radiative and radiative decay rates.…”
