Room‐Temperature Multiferroic Liquids: Ferroelectric and Ferromagnetic Order in a Hybrid Nanoparticle–Liquid Crystal System

Advanced Materials, EarlyView.
A hybrid fluid combining ferrimagnetic nanoplatelets and a ferroelectric nematic displays coexisting magnetization and polarisation at room temperature. This self‐assembled multiferroic shows strong magnetoelectric effect and nonlinear optical response, offering a soft, reconfigurable platform for next‐generation sensing, actuation, and photonic ...

Playing Hard with Si: Challenges and Opportunities for New Materials in Radiation Therapy Dosimetry

Advanced Materials, EarlyView.
Silicon has been a cornerstone material of radiation therapy dosimetry for many decades, providing somewhat unchallenged performance. However, there are caveats to its use, requiring complex designs and, often, correction factors to provide accurate measurements.

Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

Advanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

Sound, Force and Light Induced Emissions from Er3+‐Mn2+ Doped ZnS/CaZnOS Heterostructure for Remote Temperature Monitoring via Photo‐ and Mechanoluminescence

Advanced Materials, EarlyView.
Er3⁺/Mn2⁺ co‐doped ZnS/CaZnOS heterostructures are developed for remote temperature and force/sound sensing. The material exhibits UV/NIR photoluminescence, with energy transfer influencing color. Mechanoluminescence intensity is measured against applied power. Temperature‐dependent photoluminescence enabled luminescence thermometry.
