Luminescence and Photochromism in Lanthanide‐Doped Hackmanites

Advanced Optical Materials, Volume 14, Issue 23, 19 June 2026.
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

Energy‐Resolved Femtosecond Dynamics of Plasmon‐Induced Hole Injection at Au/GaN Heterointerfaces

Advanced Science, Volume 13, Issue 33, 15 June 2026.
We reveal the spectral signature of ultrafast nonthermal hot‐hole transfer at plasmonic heterointerfaces, which reshapes hot‐carrier relaxation dynamics and significantly enhances hydrogen evolution, providing a mechanistic basis for optimizing hot‐carrier utilization in photocatalysis.

Imaging and Linking Spatial Magnetic Nanoparticle Distribution to Microbead Torques Using Soft X‐Ray Laminography

Advanced Physics Research, Volume 5, Issue 6, June 2026.
Nanoscale 3D imaging of superparamagnetic microbeads via soft X‐ray laminography reveals the structural origin of the observed torques in cell movement experiments. These microbeads are found to have an uneven distribution of magnetic magnetite nanoparticles.

Enhancing Charge Transport and Extraction in Ta3N5 Photoanodes Via Ti Doping and TiN Contact Layers

Small, Volume 22, Issue 31, 2 June 2026.
Ta3N5${\rm Ta}_3{\rm N}_{5}$ is a promising photoanode for solar water splitting but suffers from poor charge transport and interfacial losses. We combine Ti compensation doping with ultrathin TiN back‐contact interlayers to suppress bulk recombination, enhance carrier mobility and lifetime, and enable efficient carrier extraction, yielding ...
