The Role of Porosity in SERS

open access: yesAdvanced Optical Materials, EarlyView.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Persistent Luminescence Analysis in the Frequency Domain

open access: yesAdvanced Optical Materials, EarlyView.
A frequency‐domain framework is introduced to characterize persistent luminescence materials. This method surpasses the limitations of time‐domain techniques and provides a new approach to understanding and optimizing the photophysical behavior of complex luminescent systems involving processes with different temporal dynamics.

Competitive Bidirectional Response in Bi‐Polymeric Mechanochromic Cantilevers Toward Color Imaging‐Based VOC Discrimination

open access: yesAdvanced Optical Materials, EarlyView.
In bi‐polymeric mechanochromic cantilevers composed of polydimethylsiloxane (PDMS) and off‐stoichiometry thiol‐ene‐epoxy (OSTE+), differential swelling between the two polymers in response to VOC exposure induces a competitive bidirectional bending and corresponding color changes, with three characteristic response modes related to the Hansen ...
