要旨

In answer to Blakey’s comment concerning the role of solution absorbance on emission spectra of gold nanoparticles (AuNP) recorded under the resonance elastic light scattering (RELS) conditions of a synchronous scan with λem = λex, we provide new evidence of a complex behaviour of plasmonic responses of functionalized AuNP down to very low concentrations, CAuNP = 7 pM. We have demonstrated that there is no threshold on the RELS spectra and that from the lowest concentration under study there is a continuous shift of the RELS peak toward longer waves. Since the absorbance of a 7 pM AuNP solution is A < 0.008, there cannot be any direct effect of A on λmax for the RELS peak and the observed approximately-linear correlation between λmax and ASP is therefore an expression of a dependence of λmax on CAuNP.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
