Abstract

The two-photon excited fluorescence spectra from CdSe quantum dots on SiN film with two-dimensional photonic crystal are studied. The fluorescence and decay process from quantum dots in solvent are compared. Two-photon excited fluorescence is enhanced by photonic crystal in vertical direction, and the blue shift of the spectrum is found on photonic crystal. The mechanism of the enhancement and the blue shift of spectrum are explained.
