We report on the study of the emission property of PbSe QDs embedded in 3D woodpile polymer PCs fabricated by the two-photon polymerization (2PP) method. Photonic band gaps (PBGs) of PCs were tuned towards longer wavelengths by infiltrating the QDs. A spectral redistribution in spontaneous emission from QDs inside a 3D PC has been measured for both low and high concentrations of infiltration.
