abstract = "We have investigated near field distribution and absorption cross-section of CdSe quantum dot (QD) conjugated gold nanoparticles using three-dimensional finite-difference time-domain method. A gold nanoparticle core was modeled with a different SiO2 shell thickness and surface density of QDs. Absorption cross-section was found to be proportionate to the shell thickness and the QD surface density. In regard to the absorption by a single QD, either nanoparticle-QD coupling or QD-QD coupling was dominant depending on the surface density. Moreover, shell thickness weakens the coupling and the absorption of a single QD. Finally, enhanced absorption by a QD-conjugated nanoparticle dimer structure is also reported as a result of field enhancement between NPs assisted by QDs.",
