External Reflection From Two‐Photon Laser‐Printed Micromirrors Enables Photomechanical Actuation at a 90° Incident Angle

Advanced Functional Materials, EarlyView.
Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

Laser Engineering of HfN‐Based Nanoparticles for Safe NIR‐I Photothermal and X‐ray Enhancing Cancer Therapies

Advanced Functional Materials, EarlyView.
In this study, we produced HfN‐based nanoparticles via femtosecond laser ablation in acetone. The nanoparticles exhibit a red‐shifted plasmonic resonance in the NIR‐I window, colloidal stability after coating with polyethyleneglycol, and excellent biocompatibility. The photothermal and X‐ray sensitization therapeutic effects were demonstrated for tumor

Beyond the Edge: Charge‐Transfer Excitons in Organic Donor‐Acceptor Cocrystals

Advanced Functional Materials, EarlyView.
Complex excitonic landscapes in acene–perfluoroacene cocrystals are unveiled by polarization‐resolved optical spectroscopy and many‐body theory. This systematic study of a prototypical model system for weakly interacting donor–acceptor compounds challenges common views of charge‐transfer excitons, providing a refined conceptual framework for ...
