A biofunctional multilayer SPR biosensor based on CsF/TiO2/Ag/CaTiO3/BP/PEG/anti‐BerEP4 is proposed for highly sensitive and selective detection of basal cell carcinoma. The sensor demonstrates enhanced performance with high sensitivity, strong resonance characteristics, and reliable differentiation between normal and cancerous cells, supporting early ...

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Analytical Characterization of Quantum Dot Enhancement Films in Commercial Displays
Colloidal quantum dots (QDs) are increasingly used in displays, yet many compositions are regulated due to hazardous metal content. Their accurate identification and assessment are therefore essential. Here, a multimodal analytical workflow centered on LA‐ICP‐MS enables spatially resolved identification and classification of QDs in commercial quantum ...

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Inter‐Theta‐Gram spectroscopy enables super‐spectral‐resolution Raman analysis by jointly reconstructing the excitation laser line and Raman peak during an etalon angle scan, yielding internally referenced Raman shifts. Demonstrated on lab‐grown versus natural diamond, it resolves 0.1–0.2 cm−1 Raman‐shift offsets that are invisible in conventional ...

Lecithin‐assisted A‐site exchange enables the formation of pure‐red perovskite quantum dots with high color purity by suppressing lattice strain and structural disorder. The resulting PeQDs exhibit a narrowed emission line‐width and enhanced chromatic stability compared to non‐assisted systems.
