520 $a Core/shell nanorods based on a plasmonic gold nanorod core with a thin dielectric shell were designed, synthesized and characterized to demonstrate their potential in photovoltaics and cancer therapy applications.
520 $a For solar cell applications, the light scattering properties of Au nanorods were combined with an electrically insulating silica (SiO2) layer to form a core/shell architecture. The Au nanorod core was coated with a SiO 2 shell in order to isolate the conductive metal surface of the gold from the conductive photo-polymers in the active layers of organic photovoltaic (OPV) devices. The aspect ratio of the Au nanorod core was spectrally tailored so that the peak extinction wavelength of the Au/SiO2 core/shell nanorod coincided with wavelength regions in which the photovoltaic material absorbed poorly. Specifically, octadecyltrimethoxysilane (OTMS)-functionalized Au/SiO2 core/shell nanorods were spectrally tailored and incorporated into two OPV polymer systems: poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCB60M) and poly[2,6-4,8-di(5-ethylhexylthienyl)benzo[1,2-b;3,4-b]dithiophene-alt-5-dibutyloctyl-3,6-bis(5-bromothiophen-2-yl) pyrrolo[3,4-c]pyrrole-1,4-dione] (PBDTT-DPP:PC60BM). For the P3HT:PC 60BM polymer with a band edge at ~ 670 nm, the incorporation of Au/SiO 2 core/shell nanospheres (radius = 20 nm) resulted in a 2.7% improvement in photon conversion efficiency (PCE). The incorporation of the core/shell nanorods (radius = 10 nm) with an aspect ratio (AR) ~ 2.5 (extinction peak, lambda peak = 670 nm) resulted in a 7.1% improvement in PCE. For the PBDTT-DPP:PC 60BM polymer with a band edge at ~ 830 nm, the incorporation of Au/SiO 2 core/shell nanospheres resulted in a 9.2% improvement, while that of core/shell nanorods (radius = 8 nm) of AR ~ 4 (extinction peak, lambda peak = 830 nm) resulted in a 14.4% improvement in PCE. The performance enhancements were corroborated by external quantum efficiency (EQE) measurements.
520 $a For cancer therapy applications, the strong light absorption properties of Au nanorods were combined with the upconverting light emission properties of rare earth doped-yttria (RE:Y2O3) in order to create hybrid plasmonic/fluorescent core/shell nanorods for dual bio-imaging and photo-thermal therapy applications. Specifically, Au/SiO2/Yb:Er:Y 2O3 core/shell nanorods were synthesized, optically characterized and tested for photo-thermal therapy both in-vitro and in-vivo. The plasmonic/fluorescent Au/SiO2/Yb:Er:Y 2O3 core/shell nanorods have a unique optical signature when excited with 980 nm laser irradiation, exhibiting both the broadband photoluminescence characteristic of Au interband transitions and the sharp emission lines characteristic of the Er3+ 4F9/2 → 4I15/2 energy transition. The Au/SiO2/Yb:Er:Y 2O3 showed a nearly two fold increase in emission compared to SiO2/Yb:Er:Y2O3 nanospheres at a wavelength of 655 nm (Er3+ 4F9/2 → 4I15/2 energy transition). Au/SiO2/Yb:Er:Y 2O3 core/shell nanorods were shown to exhibit photothermal properties upon 980 nm laser irradiation which reduced cell viability in cyto-toxicity assays and induced selective hyperthermia in breast cancer cells both in-vitro and in-vivo..
