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.

Impact of A‐Site Cation Substitution on Electronic and Optical Properties of 0D Perovskite Derivatives A4PbCl6 (A = Li, Na, K, Rb, Cs)

Advanced Photonics Research, EarlyView.
The isolated [PbCl6]4‐ octahedra, embedded in an alkali cation lattice, define the zero‐dimensional (0D) character of A4PbCl6. This work deciphers how the A‐site cation identity (from Li to Cs) governs the local electrostatic environment, thereby providing a precise strategy for tuning electronic structures and optical properties. Zero‐dimensional (0D)

Impact of Attaching Selectively Reflecting Cholesteric Layers on Edge Output of Static and Dynamic Luminescent Solar Concentrators

Advanced Photonics Research, EarlyView.
Luminescent solar concentrators (LSCs) are colorful solar energy devices designed for integration into urban settings. Their modest efficiencies partly result from excessive light surface losses . By directly coating both static and switchable LSCs with selectively reflecting chiral nematic (cholesteric) layers red‐shifted ≈70 nm to the peak emission ...

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

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...
