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)

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 ...

A graphene‐based bowtie plasmonic nanotweezer is designed and optimized using particle swarm optimization and transfer matrix analysis. The structure achieves strong field confinement, delivering trapping forces up to 6 nN W−1 for 10 nm bioparticles with sixfold lower power requirements than conventional designs.

Sharp Diamond Needles for Single‐Photon Emission
We study the morphological evolution of single‐crystal diamond needles oxidized at 650–700 °C. Electron microscopy and photoluminescence reveal temperature‐ and time‐dependent sharpening, length reduction, and surface modifications affecting tip properties.
