Progress and Prospects of Persistent Luminescent Nanocrystals in Biomedical Applications

Advanced Optical Materials, EarlyView.
This review summarizes recent progress in materials‐level control of persistent luminescence, including mechanistic understanding, wavelength/intensity tuning, and activation strategies, as well as emerging biomedical applications in imaging, biosensing, cell tracking, optogenetic stimulation, and biophotochemical activation.

Modeling and Improving Geometric Accuracy in Projection Multiphoton Lithography

Advanced Optical Materials, EarlyView.
A numerical framework describing the optical and photochemical processes is developed to elucidate the origins of geometric deviations in projection multiphoton lithography. The results indicate that oxygen diffusion and inhibition, and DMD diffraction, lead to geometric distortions.

Versatile Gasochromic Hydrogen Detection via Supraparticle‐Based Applied Composite Materials

Advanced Optical Materials, EarlyView.
Silica‐platinum‐resazurin supraparticles are embedded into PMMA to form suprabeads and thin films. The thereby obtained indicators change color from purple to pink to colorless on hydrogen exposure. The indicator systems are tested under various environmental conditions, and their performance is related to their microscopically visualized structure ...

Polarization‐Sensitive Au‐TiO2 Nanopillars for Tailored Plasmonic Enhanced Light‐Driven Reaction Activity

Advanced Optical Materials, EarlyView.
Manipulating the product generation yield is achieved on a model plasmonic resonance‐driven reaction by tuning the nonthermal effects of localized surface plasmonic resonance on an elliptical Au‐TiO2 nanopillar metasurface. Asymmetric configuration of the elliptical nanopillar array governs the polarization‐dependent optical properties redshifting the ...
