One-step synthesis of Au/porous ZrO2 SERS-active nanocomposite: Fabrication and tunable optical properties

Those organic solvents who have low-surface-tension but poor solubility towards sodium citrate are now turned round to be superiors in the synthesis of Au NPs and Au-based NCPs. The new method also provides a simple physical step that can effectively control Au NPs size, which makes the hybrids (Au/PZrO2) exhibiting novel optical properties.332
