Nanoparticles for highly efficient multiphoton fluorescence bioimaging [PDF]
, 2010 In this paper, we demonstrate for the first time that the new class of fluoride-based inorganic upconverting nanoparticles, NaYF4:Er3+, Yb3+, are the most efficient multiphoton excited fluorescent nanoparticles developed to date.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations
Advanced Materials Interfaces, EarlyView.This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Space Group Modulated Upconversion and Mechanoluminescence in [YbEu] Cocrystal Complexes
Advanced Optical Materials, EarlyView.We report here a space group regulation strategy to optimize both upconversion and mechanoluminescence in cocrystal assemblies, representing the first example of integrating these two properties within a single lanthanide complex material. ABSTRACT Lanthanide complexes exhibiting stimuli‐responsive luminescence, such as upconversion (UC) and ...
