Dynamic Modulation of Afterglow Emission in Polymeric Phosphors via Inverse Opal Photonic Structures.

Tuning the afterglow of polymeric phosphors is critical for advancing their use in optical data storage and display technologies. Despite advancements in polymer matrix design and dopant engineering, achieving dynamic control over afterglow intensity remains a significant challenge. In this study, a novel approach is introduced for dynamically tuning the afterglow of polymeric phosphors by integrating them into an inverse opal photonic structure.

Matrix-induced defects and molecular doping in the afterglow of SiO microparticles.

A deep understanding of how the host matrix influences the afterglow properties of molecule dopants is crucial for designing advanced afterglow materials. Despite its appeal, the impact of defects on the afterglow performance in molecule-doped SiO matrices has remained largely unexplored. Herein, we detail the synthesis of monodisperse SiO microparticles by hydrothermally doping molecules, such as 4-phenylpyridine, 4,4'-bipyridine, and 1,4-bis(pyrid-4-yl)benzene.
