Centrifugal Force Boosts Self‐Assembly of Gradient Lattice Photonic Crystals

Advanced Photonics Research, Volume 6, Issue 4, April 2025.
This article uses chemical synthesis to prepare size‐controllable SiO2@Fe3O4 core–shell nanoparticles and applies centrifugal force to obtain the arrangement‐controllable gradient photonic crystal. During the self‐assembly process driven by centrifugal force, Brownian motion can be neglected, and the distribution state of nanoparticles can be ...

Designing Tb3+‐Sensitized Silica‐Nanoparticles‐Aided Eu3+‐Doped Sr2SiO4 Phosphors with Enhanced Luminescence for Anti‐Counterfeiting Applications

Advanced Photonics Research, Volume 6, Issue 4, April 2025.
Silica‐nanoparticles‐assisted Eu3+‐doped Sr2SiO4 and Tb3+‐ and Eu3+‐co‐doped Sr2SiO4 phosphors are synthesized via solid‐state reaction. The co‐doping enhanced red emission by 1.78 times through energy transfer, with a decay time of 0.49 ns and 94% color purity.

Downshifting Layer of Europium‐Doped NaGdF4: From the Optimization of the Sol–Gel Process to the Luminescent Properties

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
The present approach proposes a high yield production method, using an inexpensive equipment, for the fabrication of lanthanide‐doped ternary fluoride films having high crystallinity and a very homogeneous surface. This efficient sol–gel/spin‐coating approach produces, selectively and reproducibly, the hexagonal undoped and Eu‐doped NaGdF4 films.
