High‐Resolution Stereolithography of Amorphous, Dense and Mechanically Stable Bioactive Glass

open access: yesAdvanced Materials Technologies, EarlyView.
Porous scaffolds made of bioactive glass are of great interest for bone tissue engineering. The geometry and resolution of the scaffold is impacting its bioactive and mechanical performance. Utilizing stereolithographic 3D printing of bioactive glass, human cancellous bone scaffolds, and other structures are fabricated with features as small as 77 µm ...

Drastic Mechanochromic Luminescence Through Fluorescence–Phosphorescence Switching in a Heavy‐Atom‐Free Organoboron Compound

open access: yesAdvanced Optical Materials, EarlyView.
A new heavy‐atom‐free, donor–acceptor‐type organoboron luminophore has been synthesized, which exhibits red room‐temperature phosphorescence (RTP) in the crystalline state. Furthermore, the amorphous solid generated by grinding shows green thermally activated delayed fluorescence (TADF), displaying distinct mechanochromic luminescence (MCL) through ...

Bright LaF3:Eu@Ir Phosphors Combining Two‐Photon Excitation, d → f Energy Transfer and Tunable Time‐Gated Chromaticity for Multicolor Cell Imaging

open access: yesAdvanced Optical Materials, EarlyView.
The surface functionalization of Eu‐doped LaF3 particles with a two‐photon absorbing IrIII complex results in the formation of ultrabright Eu:LaF3 phosphors, which exhibit a combination of short‐lived IrIII and long‐lived EuIII‐sensitized emissions. These Ir/Eu hybrids are effectively internalized by HEK‐293 cells without causing toxic effects, thereby

Tunable‐Wavelength Broadband Liquid‐State Carbon‐Quantum‐Dot Lasers

open access: yesAdvanced Optical Materials, EarlyView.
This work provides a gain‐induced waveguide structure to achieve programmable mode spacing by coupling liquid‐state lasing of carbon quantum dots to a vertically placed aluminum mirror, enabling an unprecedented transition from random lasing to multimode lasing without cumbersome micromanufacturing, even single‐mode lasing at a wide range from 641 to ...

Liquid Metal‐Exfoliated SnO2‐Based Mixed‐Dimensional Heterostructures for Visible‐to‐Near‐Infrared Photodetection

open access: yesAdvanced Optical Materials, EarlyView.
Two dimensional (2D) atomically thin materials hold significant promise for next‐generation photodetectors but are limited by low light absorption and scalability challenges. This study presents a high‐performance photodetector integrating liquid metal‐derived 2D SnO2 with CdTe, enabling efficient visible to near‐infrared detection and offering a ...

Understanding the Role of Fabry‐Perot Resonances in Maximizing Absorption for Ultrathin Sn Halide Perovskite Optoelectronic Devices

open access: yesAdvanced Optical Materials, EarlyView.
A design principle is presented that maximizes absorption in ultrathin (tens of nanometers) Sn halide perovskite optoelectronic devices by aligning their intrinsic absorption wavelengths with Fabry–Pérot (FP) resonances. The ultrathin FASnI3 devices exhibit increases open‐circuit voltage, reduces dark current, and high photocurrent, yielding high ...

Pyroelectric Doping Reversal of MoS₂ p‐n Junctions on Ferroelectric Domain Walls Probed by Photoluminescence

open access: yesAdvanced Optical Materials, EarlyView.
The potential of pyroelectricity for controlling electron doping in monolayer MoS2 on periodically poled LiNbO3 substrates is demonstrated. Pyroelectric charges are shown to convert p‐n into n‐p homojunctions formed in MoS2 on domain walls. The variation in the MoS2 electron density from 300 to 10 K is consistent with the change in the spontaneous ...
