Abstract Quantum mechanical effects in plasmonic nanocavities have attracted strong interest the last two decades, related to both their experimental realization and implementation technological applications, challenges that need be overcome theoretical modeling. This review summarizes basic theories of quantum plasmonics, its modeling strategies, material systems support it. Particularly it is focused on recent progress plasmonics based nanoparticle‐on‐mirror (NPoM) structure, i.e., nanoparticles separated from an underlying metallic substrate via ultrathin spacer, which provides elegant route toward cost‐effective fabrication a large number similar cavities. A dramatic shift research trends seen applications nano‐optics, polaritonics, chemistry, biosensing, gradually making transition fundamental, curiosity‐driven applied science.

Abstract This perspective article addresses the potential of colloidal metasurfaces composed emitting and plasmonic nanoparticles to advance applications in nanophotonics. Leveraging synergy advanced laser interference lithography (LIL) template‐assisted self‐assembly (TASA), latest advances directed nanoparticles, enabling precise manipulation photonic properties, are presented. These methods enable improved responses, such as increased emission intensity, directional enhancement, tunable bandgaps. Key this approach is rational design nanostructures that optimize interactions between localized collective optical modes achieve synergistic improvements functionality through mechanisms surface lattice resonances (SLRs) hybridized guided mode (hGMRs). Developments metasurface design, supported by theoretical studies simulations demonstrate scalability effectiveness hybrid fabrication approach, emphasized. include high‐efficiency light‐emitting devices, low‐threshold lasing, surface‐enhanced Raman spectroscopy (SERS) with high sensitivity large‐area uniformity. improve low‐loss sensing provide platform for transformative technologies quantum computing, secure communication networks, optoelectronic systems.

Chiral luminescence holds promise for various applications, but achieving strong, pixelated emission with a large dissymmetry factor (glum) on-chip integration remains challenging. Here we address this challenge by optically growing CdS emitters within the superchiral fields of Au spiral metasurfaces. This precise placement enhances emitter-field interaction, yielding chiral photoluminescence glum up to ∼0.5 and an ∼30-fold intensity enhancement. We demonstrate that both excitation wavelength emitter location significantly impact quality, highlighting critical role resonant spatial alignment fields. These findings provide crucial guidelines designing high-performance devices suitable photonic integration.

Abstract Active chiral plasmonics show promise for sensing and light generation applications. While progress in fabricating plasmonic nanostructures has advanced, their fixed chiroptic properties limit device functionality, structure‐chiroptic correlations remain poorly understood. a superplastic nanomolding technique is introduced to form single‐crystalline metal helices. Single‐crystalline silver helices demonstrate strong responses with dissymmetry factors up ≈0.4, matching simulations. By mechanically manipulating individual helical nanowires, reversible tuning of achieved, reveal structure‐chirality correlations. This approach offers scalable fabrication method mechano‐tunable while providing design guidelines improved detection devices.
