摘要：
A one-pot synthetic strategy was developed for fabrication of hollow gold nanoshells by direct reduction of HAuC14 in 3-aminopropyltriethoxysilane (APTES)-in-water suspension. Diameters of the APTES droplets which may act as templates for the hollow gold nanoshells could be readily tuned by changing the concentration of HAuC14 used in the reactions. This flexibility facilitated the tailoring of the sizes of the gold naoshells in the range of 37-96 nm and their corresponding surface plasmon resonance (SPR) in the visible and near infrared region of 657-957 nm. The as-prepared hollow gold nanoshells showed high photothermal conversion efficiency (up to 45%) and excellent stability under laser irradiation. (C) 2016 Elsevier B.V. All rights reserved.
