Illuminations for constructions of scintillating lanthanide–organic complexes in sensitive X-ray detection and high-resolution radiative imaging

Post-synthetic functionalization of Zn-CP by Tb3+ ions: a ratiometric luminescent sensor for the ultraviolet filter benzophenone

“…Particularly, luminescent coordination polymers (CPs) or metal organic frameworks (MOFs) have become an important class of luminescence sensing materials, which have achieved the detection of ions, molecules, pH, temperature, and so on. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] So far, only one reported MOF-based luminescent probe is used to detect BP-type UVFs, 10 and it is a single emission luminescent probe. However, such a probe is easily disturbed by factors such as equipment, material concentration and the environment.…”

Emerging Nanoagents for Medical X-ray Imaging

“…In addition to X-ray attenuation-based contrast nanoagents, the emergence of X-ray luminescence nanoagents has promoted the development of advanced X-ray imaging techniques. Owing to the unlimited penetration and free autofluorescence of X-rays, X-ray luminescence-based in vivo imaging is affordable for high detection sensitivity and high imaging quality in deep tissues. − Since X-ray-activated near-infrared (NIR) luminescence possesses low photon absorption and scattering in tissues, the utilization of such nanoprobes could drastically increase the sensitivity and resolution of X-ray imaging and benefit diagnosis and therapy. − Moreover, X-ray-activated persistent luminescence nanoparticles have also been explored to avoid injuring healthy tissues by X-ray irradiation. − Thus, the advent of these X-ray luminescence nanomaterials as a new type of nanoagent has led to a significantly expanding toolbox for advanced X-ray imaging in diagnostic technologies.…”

Designing scintillating coordination polymers using a dual-ligand synthetic approach

“…Published examples of lanthanide CPs that scintillate range in dimensionality and almost always feature Eu 3+ or Tb 3+ ions paired with aromatic chromophores. 35,61–65 For example, Wang et al reported Tb 3+ and Eu 3+ isostructural scintillating CPs that were constructed from oxalate and phen ligands. 61 In the same study, a similar Eu 3+ CP that contained only the oxalate ligand did not exhibit analogous behavior; thus, the phen ligands are thought to serve an essential mechanistic role.…”
