摘要：
We have fabricated opal photonic crystal structure, which is assembled from quantum dots-conjugated polystyrene spheres. We found that the quantum dots (QD) emission from QD-conjugated photonic crystal (PC) structure experienced not only shifting to shorter wavelength, but also an asymmetrical broadening. This photonic crystal structure uses less quantum dots and may lead to great application such as single photon source and QD laser, since we may sharpen and broaden the QD emission by selecting the proper position of stop band.
