Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to our Special Issue entitled “Advancing Nanophotonic Materials: Fundamentals and Applications”. As a rapidly evolving interdisciplinary field, nanophotonics has garnered significant attention due to its potential to revolutionize various technological domains. This area of research area is crucial as it promises to deliver novel solutions to the key challenges associated with energy, healthcare, and information technology.

This Special Issue aims to curate a comprehensive collection of articles that not only contribute to our fundamental understanding of nanophotonic materials but also showcase their diverse applications. In alignment with the scope of the journal, which encompasses the broader field of materials science and engineering, we hope to create a Special Issue that is both scientifically rich and technologically relevant. We aim to compile at least 10 high-quality articles, potentially leading to the publication of this Special Issue in book form.

We welcome original research articles and reviews that delve into various aspects of nanophotonic materials. The scope of this Special Issue includes, but is not limited to, the following topics:

  • The synthesis and characterization of novel nanophotonic materials;
  • The theoretical and computational modelling of nanophotonic phenomena;
  • Applications in renewable energy, such as advanced solar cells;
  • The development of nanophotonic sensors and imaging techniques;
  • Innovations in communication technologies using nanophotonic devices;
  • Metamaterials and their unique optical properties.

We look forward to receiving your contributions and believe that together we can create a Special Issue that will serve as a valuable resource for the scientific community.

We investigate the linear and nonlinear optical properties of (sub-nm) Ag6 and Au6 clusters doped with Sc and Y using time-dependent density functional theory. Both parent clusters have D3h ground-state geometries but exhibit noticeably different electronic structures; scalar-relativistic corrections in Au6 induce significant s-d hybridization, resulting in larger HOMO-LUMO gaps and reduced one-photon absorption (OPA) cross-sections compared to Ag6. Two-photon absorption (TPA) peaks in the UV region show resonance enhancement via coupling with OPA-active states, with Ag6 having larger cross-sections than Au6. Doping with Sc and Y modifies the optical responses by breaking configurational symmetry and lifting HOMO degeneracies. ScAg5 and YAg5 energetically prefer planar configurations with higher dopant orbital contributions, while ScAu5 and YAu5 prefer non-planar configurations. This leads to blue-shifted, intensified OPA transitions and larger TPA cross-sections in doped clusters than in parent clusters. Doped Ag clusters exhibit a significantly stronger TPA response in the biologically relevant 1.8–2.0 eV (620–690 nm) spectral region for in vivo imaging. Furthermore, a higher degree of Sc(Y)-Au hybridization generates additional TPA pathways and also facilitates electronic transitions at 1064 nm, enhancing the first hyperpolarizability (β (−2ω; ω, ω)) for YAu5. Overall, the results show that these (sub-nm) Sc/Y-doped noble metal clusters are promising candidates for photonic and biomedical imaging applications. Full article
