Pseudo‐Dichroism: Nanophotonic Induction of Chiroptical Activity in Symmetric Molecular Systems
By analyzing vibrational circular dichroism (VCD) spectra of chiral nanomaterials, we distinguish genuine molecular chirality (true dichroism) from measurement artifacts (pseudo dichroism) using a novel, robust framework. The spectral criteria we establish apply broadly to all chiroptical techniques in nanomaterial research, enhancing precision in ...

The AuAgNCs@OSTE nanocomposite, fabricated using off‐stoichiometric thiol‐ene polymerization, incorporates Au23‐xAgx(SAdm)15 nanoclusters and OSTE monomer. After UV curing, it reaches a maximum PLQY of 73% at 740 nm after 20 h of UV curing. After 72 h UV curing, PLQY reaches 60% at 850 nm, with minimal reabsorption losses due to the higher Stokes shift.

Non‐Reciprocal Terahertz Topological Sensor on a Silicon Chip
A non‐reciprocal terahertz topological sensor (NTTS) is experimentally demonstrated on a silicon valley photonic crystal chip by detecting the thickness and position changes of a polyimide membrane. The sensor exploits detuning between clockwise and counterclockwise topological cavity modes, induced by integrated magneto‐optical InSb, to achieve non ...

Resonance Energy Transfer and Purcell Effect in a Cu2O/Au Hybrid Optical Antenna
A Cu2O nanosphere mediates efficient (e.g., 70%) resonance energy transfer (RET) to a gold substrate. The RET damping constant derived from single‐particle scattering, ΓRET$\left(\Gamma\right)_{R E T}$, identifies interband transitions in Au. RET also occurs from an excited electron‐hole pair in Au to the Cu2O/Au hybrid resonator mode, followed by ...
