We investigate the effects of a silica spacer layer on this fluorescence enhancement. Numerical simulations using the Finite- Difference Time Domain (FDTD) method is performed to find the optimum size for the gold nanosphere core as well as the optimum thickness of the silica shell. We present the dependence of radiative decay rate and quantum yield of the fluorescent molecule with respect to varying silica layer thicknesses. © 2010 Copyright SPIE - The International Society for Optical Engineering. | Source Title: | Progress in Biomedical Optics and Imaging - Proceedings of SPIE | URI: | http://scholarbank.nus.edu.sg/handle/10635/73692 | ISBN: | 9780819479730 | ISSN: | 16057422 | DOI: | 10.1117/12.841747 |
