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

open access: yesAdvanced 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)

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

open access: yesAdvanced 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 ...

Revealing Two Operation Modes of Perovskite Light‐Emitting Diodes Through Overshoot Pulses

open access: yesAdvanced Photonics Research, EarlyView.
Short, high‐intensity overshoot pulses (OSPs) may be generated by perovskite light‐emitting diodes (PeLEDs) depending on electrical pump pulse parameters, offset and afterpulse voltages. OSPs reveal two PeLED operation modes: the recombination mode, favorable for the conventional EL but preventing OSPs, and the accumulation mode, enabling the formation
