Size Effect on Photothermal Heating Ability of Gold Bipyramids

open access: yesAdvanced Optical Materials, EarlyView.
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Relation of Continuous Chirality Measure to Spin and Orbital Polarization, and Chiroptical Properties in Solids

open access: yesAdvanced Optical Materials, EarlyView.
This work quantifies chirality through the continuous chirality measure (CCM). The CCM is correlated to a variety of properties: spin‐orbit field, orbital angular momentum, circular dichroism, absorption dissymmetry factor (gCD) and the circular photogalvanic effect.

The Role of Optical Centers in Neodymium‐Doped Calcium Fluoride: Optical Tagging and Nanothermometry in the Second Biological Window

open access: yesAdvanced Optical Materials, EarlyView.
Tuning excitation by only 6 nm unveils three distinct optical centres in CaF2:Nd3⁺,Y3⁺, each with unique spectral fingerprints. Some exhibit properties ideal for precise nanoscale temperature sensing. Abstract Nd3+ has been proposed for nanothermometry in biological media, as both its emission and excitation wavelengths fall within the regions of low ...

Evolution of Collective, Radiative Plasmon Coupling in Confined, Soft Colloidal Films

open access: yesAdvanced Optical Materials, EarlyView.
Plasmon resonance coupling is continuously monitored during the uniaxial manipulation of a 2‐dimensional soft colloidal film containing hexagonally arranged spherical gold nanocrystals. This is realized by the in situ spectroscopic investigation of a monolayer of plasmonic core‐shell microgels confined at the air/water interface that is compressed in a

Graded Plasmonic Metagratings for Directional Nonlinear Optical Sensing

open access: yesAdvanced Optical Materials, EarlyView.
A refractometric sensing approach is presented, based on the angular variation of the emission pattern while changing the local environment. This method is first demonstrated on rectangular arrays, then on an aperiodic metagrating configuration designed to shape the first diffraction orders into a broadened band. Abstract Plasmon‐enhanced sensing based
