Synthesis of Ag–Ag2S@Ag–Au Hybrid Nanoparticles by Seed Mediated Growth Synthesis of Ag–Ag2S Nanoplates and Their Photothermal Application |
| 초록 |
Seed-mediated growth synthesis is a facile approach that has been exploited to manufacture a well-defined structure of nanoparticles. Recent studies on seed-mediated growth synthesis to obtain hybrid metal–semiconductor nanoparticles are mostly worked on the deposition of metal to semiconductor nanoparticles resulting in hybrid metal–semiconductor nanostructures with small metal islands on the surface of semiconductor. Herein, we report a simple method to develop new hybrid heteronanostructures based on seed-mediated growth synthesis of hexagonal Ag–Ag2S hybrid nanoplates to obtain metal–semiconductor@metal core@shell hybrid nanoparticles. Through galvanic replacement reaction, the as-synthesized core@shell nanohybrids were transformed to porous structures of metal–semiconductor@bimetallic hybrid nanoparticles. The new heteronanostructures were employed as photothermal materials and exhibited high photothermal performances. |
