Transition‐Metal Azo Schiff Base Complexes: Nonlinear Optics Across Solutions, Thin Films and Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
The excitation of a transition‐metal azo Schiff‐base complex with a 1064 nm laser induces a series of nonlinear optical effects. These effects include the second harmonic generation at 532 nm and third harmonic generation at 355 nm. This process demonstrates the potential of the complex for high‐order nonlinear optical applications. Abstract This paper

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 ...

Precision‐Engineered Plasmonic Nanostar Arrays for High‐Performance SERS Sensing

open access: yesAdvanced Optical Materials, EarlyView.
Highly ordered and dose‐controlled arrays of gold nanodiscs are created using the dots‐on‐the‐fly EBL technique and subsequently converted into nanostar arrays. This technique unlocks the reproducible and robust fabrication of highly efficient SERS substrates. Abstract Surface‐enhanced Raman scattering (SERS) spectroscopy has emerged as a powerful tool

Wrinkle‐Template Confinement of Kinetically Arrested Cellulose Nanocrystals for Sustainable Large Scale Reflection Gratings

open access: yesAdvanced Optical Materials, EarlyView.
Self‐supported all‐cellulose reflective gratings are fabricated from cellulose nanocrystal dispersions via a confinement printing process. Taking advantage of the reduced fluidity of concentrated, kinetically arrested cellulose nanocrystal dispersions, line arrays can be successfully transferred to dried CNC films.

Organic, Transparent, and Flexible Films Exhibiting White‐Light Emission via Polymer‐Network Engineering: A Non‐Dye‐Centric Strategy

open access: yesAdvanced Optical Materials, EarlyView.
A hydrogel‐based white light‐emitting (WLE) material is synthesized, where emission results from the synergistic interaction of two complementary dyes embedded in the polymer matrix. By tuning the monomer and cross‐linker composition, the system achieves balanced white light fluorescence with high transparency and flexibility, showcasing a matrix ...
