Two-photon excited fluorescence from colloidal quantum dots on SiN photonic crystals


Xingsheng Xu, Toshiki Yamada, Shiyoshi Yokoyama


Abstract

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