Gold nanoparticles (∼6 nm) were deposited on the surface of silica shell of these core/shell/shell nanoparticles. The total upconversion emission intensity (green, red, and blue) of the core/shell/shell nanoparticles decreased by ∼31% after Au was deposited on the surface of silica shell. The upconverted green light was coupled with the surface plasmon of Au leading to rapid heat conversion. These UC/silica/Au nanoparticles were very efficient to destroy BE(2)-C cancer cells and showed strong potential in photothermal therapy. © Springer Science+Business Media B.V. 2010. | Source Title: | Journal of Nanoparticle Research | URI: | http://scholarbank.nus.edu.sg/handle/10635/86375 | ISSN: | 13880764 | DOI: | 10.1007/s11051-010-0080-6 |
