This research demonstrates a seedless technique for synthesizing gold nanorods with tunable plasmon wavelengths, highlighting kinetics differences from seed-mediated methods.
Key Points
The seedless synthesis method produces gold nanorods with diameters as low as 9.9 nm and a tunable plasmon wavelength between 658 and 1028 nm.
The study reveals that the kinetics of gold seed formation critically impact the shape yield and monodispersity of the nanorods.
Gold nanorods exhibit a high shape yield due to the use of m-phenylenediamine as a reducing agent, differentiating from traditional methods.
Understanding the mechanisms of the seedless approach enhances the ability to fabricate nanoparticles with specific properties.
