Scintillators, which are capable of converting ionizing radiation into visible photons, an integral part medical, security, and commercial diagnostic technologies such as X-ray imaging, nuclear cameras, computed tomography. Conventional scintillator fabrication typically involves high-temperature sintering, generating agglomerated powders or large bulk crystals, pose major challenges for device integration processability. On the other hand, colloidal quantum dot scintillators cannot be cast...
A new class of lanthanide-doped upconversion nanoparticles are presented that without Yb3+ or Nd3+ sensitizers in the host lattice. In erbium-enriched core-shell NaErF4 :Tm (0.5 mol %)@NaYF4 nanoparticles, a high degree energy migration between Er3+ ions occurs to suppress effect concentration quenching upon surface coating. Unlike conventional -Er3+ system, ion can serve as both sensitizer and activator enable an effective process. Importantly, appropriate doping Tm3+ has been demonstrated...
This paper reports a droplet-based microfluidic approach to fabricate large number of monodisperse, portable microtissues, each in an individual drop. We use water-water-oil double emulsions as templates and spatially assemble hepatocytes the core fibroblasts shell, forming 3D liver model
Scintillators that exhibit X-ray-excited luminescence have great potential in radiation detection, X-ray imaging, radiotherapy, and non-destructive testing. However, most reported scintillators are limited to inorganic or organic crystal materials, which some obstacles repeatability processability. Here we present a facile strategy achieve the phosphorescent scintillation from amorphous copolymers through copolymerization of bromine-substituted chromophores acrylic acid. These polymeric...
Luminescence clusters composed of organic ligands and metals have gained significant interests as scintillators owing to their great potential in high X-ray absorption, customizable radioluminescence, solution processability at low temperatures. However, luminescence efficiency is primarily governed by the competition between radiative states from nonradiative cluster-centered charge transfer. Here we report that a class Cu4I4 cubes exhibit highly emissive radioluminescence response...
Abstract Lead halide perovskites have made great advance in direct X‐ray detection, however the presence of toxic lead and requirement high working voltages severely limit their applicability operational stability. Thus, exploring “green” lead‐free hybrid capable detecting X‐rays at zero bias is crucial but remains toughly challenging. Here, utilizing chiral R / S ‐1‐phenylpropylamine ( ‐PPA) cations, a pair 0D chiral‐polar perovskites, 2 BiI 5 1 ) are constructed. Their intrinsic...
Abstract Achieving efficient photon upconversion under low irradiance is not only a fundamental challenge but also central to numerous advanced applications spanning from photovoltaics biophotonics. However, date, almost all approaches for luminescence intensification require stringent controls over factors such as composition and size of nanophosphors. Here, we report the utilization dielectric microbeads significantly enhance processes in lanthanide-doped nanocrystals. By modulating...
