Tailoring Chiral Gold Nanorods via Single‐Step Seed‐to‐Au(III) Ratio and Unlocking their Potential in Refractive Index Sensing

Advanced Optical Materials, EarlyView.
A single‐step tunable chiral growth of Au NRs with controllable circular dichrosim (CD) response is reported, and the application of narrow CD response for biosensing with superior Figures of Merit (FoM = RIS/linewidth) over conventional extinction‐based approach in sensitivity is demonstrated.

Strategies to Maximize the Dopant‐To‐Exciton Emission Ratio in Mn‐Doped CsPbCl3 Nanocrystals

Advanced Optical Materials, EarlyView.
Different strategies, such as dopant concentration, bandgap of host, co‐doping, and surface passivation, are investigated to maximize the dopant‐to‐exciton emission ratio of Mn2+‐doped CsPbCl3 nanocrystals (NCs). While the dopant concentration and host's bandgap are crucial, co‐doping and surface passivation significantly enhance the energy transfer ...

Self‐Aligned Pillar Arrays Embedding Site‐Controlled Single Quantum Dots for Bright Nonclassical Light Emission

Advanced Photonics Research, EarlyView.
Tilted‐view scanning electron microscope images show arrays of self‐aligned etched GaAs triangular pillars hosting single quantum dots. The main image captures the as‐fabricated morphology prior to dielectric coating, highlighting their uniform geometry.

VO2 Nanocomposite Thin Films Integrated on Glass Substrates for Tunable Properties

Advanced Photonics Research, EarlyView.
This work explores tuning the metal‐to‐insulator transition and optical properties through a novel multifaceted approach using both defect engineering and energy band restructuring. VO2‐Au nanocomposite and VO2 thin films are grown on glass with ZnO buffers using pulsed laser deposition.

Photoluminescence Properties of Type‐II GaSb/GaAs Quantum Rings

Advanced Photonics Research, EarlyView.
This study examines the magneto‐optical properties of GaSb/GaAs quantum rings (QRs) using photoluminescence spectroscopy. Recombination dynamics in single‐ and ten‐layer structures are analyzed through activation energy extraction, optical absorption profiling, and observation of a strong excitation‐induced blue shift. Carrier lifetime is also increase
