Summary of particle size of the noble metal NP systems determined by DLS, TEM, UV–visible spectroscopy and XRD
| System | DLSa (nm) | TEM (nm) | UV–visible (nm) | XRDb (nm) |
|---|---|---|---|---|
| Ag/AuNPs | 9.4±2.8 | 9.7±3.2 | ~7 | 10.3±4.5 |
| AuNPs | 29.3±8.6 | 28.5±2.0 | 27.4±2.0 | 22.5±9.9 |
Notes:
a
Values for DLS correspond to hydrodynamic diameter.
b
Values for XRD correspond to crystallite size (L).
Abbreviations: AgNPs, silver nanoparticles; AuNPs, gold nanoparticles; DLS, dynamic light scattering; NP, nanoparticle; TEM, transmission electron microscopy; UV, ultraviolet; XRD, X-ray diffraction.
