Imparting Biodegradability to Highly‐Efficient Upconversion Nanoparticles via Facet‐Selective Zirconium Doping

open access: yesSmall, EarlyView.
A simple incorporation of Zr imparts biodegradability to inherently inert rare‐earth‐based upconversion nanoparticles without compromising optical performance. Surface energy modulation of LiREF4 facets by a binary‐surfactant system enables Zr incorporation during hot‐injection synthesis.

Minimizing Defects in Blue‐Emitting ZnSeTe Quantum Dots Using ZnF2 Throughout Core and Shell Growth

open access: yesSmall, EarlyView.
Near‐unity photoluminescence quantum yield (PLQY = 0.98) in blue ZnSeTe quantum dots is achieved by integrating ZnF2 throughout all growth stages. ZnF2 performs two key functions: generating HF in situ for structural defect removal and simultaneously promoting X‐ and Z‐type ligand attachment for effective surface passivation.

Electrically Tunable Tunneling and Spectral Response in WSe2/h‐BN/CdSe/Graphene Heterostructure

open access: yesSmall, EarlyView.
In the WSe2/h‐BN/CdSe quantum dot/graphene heterostructure, the graphene voltage dynamically tunes the tunneling barrier and energy alignment across the h‐BN layer. The bias‐dependent Fermi‐level alignment enhances the tunneling density of states, leading to efficient extraction of photo‐excited electrons from QDs into WSe2 and graphene.

Qualitative Evaluation of the Magnetocrystalline Anisotropy in Spinel Ferrite Nanoparticles Using Polarized Neutron Powder Diffraction

open access: yesSmall, EarlyView.
Polarized neutron powder diffraction is used to qualitatively probe the magnetocrystalline anisotropy of cobalt‐doped ferrite nanoparticles. The analysis of local magnetic susceptibility tensors and magnetization ellipsoids reveals how cobalt incorporation modifies both the magnitude and orientation of anisotropy, providing a new approach to compare ...

Synthesis of Samarium‐incorporated X‐ray‐sensitive nanoparticles and hydrogels: Diverse applications in radiation monitoring and dynamic information display

open access: yesSmart Molecules, EarlyView.
Sm3+‐doped α‐NaLuF4 and β‐NaLuF4 were synthesized. The X‐ray‐activated persistent luminescence abilities and afterglow properties can be well controlled. Sm3+‐doped β‐NaLuF4 exhibits remarkable afterglow ability. The hexagonal β‐NaLuF4:3%Sm3+‐incorporated hydrogel can be further programmed with other types of hydrogels to enable tunable emission ...
