Microdroplet Magnetic Field Sensor Utilizing Magneto‐Birefringence Effect

open access: yesAdvanced Materials Technologies, EarlyView.
A compact sensor based on birefringent microdroplets of magnetic nanoplatelet suspension enables precise optical detection of magnetic field strength and direction at the microscale. The system offers high sensitivity, fast response, and compatibility with lab‐on‐chip applications.

Understanding and Circumventing Failure Mechanisms in Chalcogenide Optical Phase Change Material Ge2Sb2Se4Te

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

Finding the unusual red giant remnants of cataclysmic variable mergers

open access: yesThe Open Journal of Astrophysics
Mergers between helium white dwarfs and main-sequence stars are likely common, producing red giant-like remnants making up roughly a few percent of all low-mass ($\lesssim2M_\odot$) red giants.

Simultaneous Emission Spectral Narrowing and Spin‐Flip Acceleration in Multi‐Resonance Organoboron Emitters via Sequential Indolo‐Fusion π‐Extension

open access: yesAdvanced Optical Materials, EarlyView.
Sequential indolo‐fusion π‐extension as a rational design strategy to further narrow the emission bandwidth of multi‐resonance thermally activated delayed fluorescence is introduced. By fusing one or two additional indole moieties to the periphery of Cz‐B, gradual spectra narrowing and accelerated triplet–singlet exciton spin conversion are ...

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
