This work presents trap‐programmable Ruddlesden–Popper perovskite nanocrystals for ultralong‐lived optical memory and photonic synapses. Layer‐controlled octahedral distortion modulates trap depth and carrier‐storage kinetics, enabling persistent luminescence beyond 5000 s at room temperature.

Unraveling the Effects of Depolarization in Ultrathin Barium Titanate
This article employs synchrotron‐based spectroscopy, time‐resolved electrical measurements, and phase‐field simulations to establish reverse‐domain formation as the mechanism of polarization loss in ultrathin BaTiO3${\rm BaTiO}_3$ films as a critical obstacle to low‐voltage ferroelectric devices.

CsPbI3 nanostructures integrated with g‐C3N4 formed S‐scheme heterojunctions enabling efficient photocatalytic CO2 reduction and NO abatement. The g‐C3N4/CsPbI3 nanowires achieved a CO production rate of 4.6 µmol g−1 h−1, while nanocrystal composites delivered 69.5% NO removal with only 5.0% NO2 selectivity, driven by highly energetic charge carriers ...

Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films
The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.

CW‐Pumped Amplified Spontaneous Emission From Thermally Evaporated CsPbBr3 Films
Thermally evaporated CsPbBr3 thin films sustain amplified spontaneous emission from short‐pulse toward quasi‐continuous‐wave excitation. Time‐resolved spectroscopy, controlled excitation, and substrate engineering reveal how excitation duration governs optical‐gain stability.
