Abstract
The emission behaviors of CdSe/ZnS core-shell quantum dots (QDs) in proximity to the surface of a three-dimensional photonic crystal (PC) are investigated experimentally and theoretically. Results show that the spontaneous emission (SE) of QDs in such a structure presents a damped periodic oscillation with the distance between QDs and the PC surface, and the most significant modification always appears in the short-wavelength region, resulting from the coefficient of surface modes and interference between the direct SE field and the reflected SE field. These display a wide range of novel optical properties for many applications in optoelectronic devices.
