Highly Crystalline CsPbBr3 Thin Films With Amplified Spontaneous Emission via High‐Pressure Recrystallization

open access: yesAdvanced Optical Materials, EarlyView.
High‐pressure recrystallization provides a reproducible route to high‐quality CsPbBr3${\rm CsPbBr}_{3}$ thin films. Optimized processing at 300 bar yields smooth, pinhole‐free, single‐phase 3D perovskite layers with tunable thickness, enhanced crystallinity, reduced amplified‐spontaneous‐emission threshold, improved photostability, and phase‐transition

From Molecular Design to Optical Anisotropy: Orientation Control in BODIPY Langmuir‐Blodgett Films

open access: yesAdvanced Optical Materials, EarlyView.
The supramolecular organization of amphiphilic boron‐dipyrromethene (BODIPY) dyes in Langmuir–Blodgett monolayers is shown to govern their optical anisotropy. By correlating nanoscale imaging and angle‐resolved spectroscopy, we reveal symmetry‐driven control of transition dipole orientation, enabling either in‐plane or out‐of‐plane optical responses ...

Confinement‐Induced Nonlocality and Optical Nonlinearity of Transdimensional Titanium Nitride Films in the Epsilon‐Near‐Zero Region

open access: yesAdvanced Optical Materials, EarlyView.
The epsilon‐near‐zero (ENZ) effect in metals emerges only in nanometer‐scale films with exceptional optical quality. Titanium nitride (TiN) films grown by molecular beam epitaxy retain high crystallinity down to 2 nm and exhibit dramatically enhanced nonlinear optical responses near the ENZ region.

1.5 µm Emission Properties of Erbium‐Implanted Thin‐Film Lithium Niobate

open access: yesAdvanced Optical Materials, EarlyView.
Optically active Er3+ ions are incorporated into x‐cut lithium niobate on insulator utilising a focused ion‐beam implantation method capable of sub‐100 nm precision. The implanted regions exhibit telecom‐band emission, with a reduction in photoluminescence intensity and lifetime below 50 K, consistent with pyroelectric‐field effects in the host ...
