Abstract

Photoluminescence decays from PbSe quantum dots (QDs) at different depths inside a 3D woodpile photonic crystal (PC) are investigated. The figure demonstrates that the average lifetimes of QDs with emitting wavelengths within the band gap region increase when the excitation position moves into the structure, indicating the inhibition of QD emission by the stop gap of the PC.
