Barium(II)-based semiconductive coordination polymers for high-performance direct X-ray detection and imaging: Reducing the exciton binding energy via enhancing π-π interactions

X-ray-triggered through-space charge transfer and photochromism in silver nanoclusters

“…Among them, photochromic functional materials have demonstrated practical application value and hold potential for further development in various fields such as optics, magnetism, imaging, and characteristic substance detection. 1–22 Inorganic, organic, and organic–inorganic hybrid materials could demonstrate photochromism, each of which offers unique properties and characteristics. Inorganic materials such as spinel CuIr 2 S 4 , lithium niobate crystals (LiNbO 3 ), and sodalite (Na 8 A l6 Si 6 O 24 (Cl,S) 2 ) have been reported to show both UV- and X-ray-induced reversible color change.…”

Efficient X-ray Detection of Polyoxometalates@Metal–Organic Frameworks Based on Host–Guest Electron Transfer

“…To explain the reason for the distinct performance difference between 1 and 2, the detection mechanism in MOFs was investigated, which is closely related to the following three processes: the X-ray absorption and conversion (α), charge carrier transport (β), and charge collection (γ). 6,23 The simulated X-ray absorption coefficient and attenuation efficiency show that 2 has higher absorbance and attenuation abilities for X-ray photons compared to those of 1 (Figures 3a and 3b). The effective atomic number Z eff was calculated to further quantify the X-ray blocking capability.…”

“…Furthermore, there are significant differences in the X-ray detection performance of isomorphic 1 and 2 , which qualitatively concludes that the different guest POMs in MOFs are involved in X-ray detection. To explain the reason for the distinct performance difference between 1 and 2 , the detection mechanism in MOFs was investigated, which is closely related to the following three processes: the X-ray absorption and conversion (α), charge carrier transport (β), and charge collection (γ). , …”

“…5 The novel hybrid perovskites have excellent carrier transport properties and high X-ray absorption, but the poor stability and intrinsic ion migration remain to be addressed. 6 Metal−organic frameworks (MOFs) are porous materials assembled from inorganic nodes and organic ligands, with the advantages of tunable functions, designable structures, and mild synthesis processes. 7 With the characteristics of high on/ off ratio, low dark current, and excellent irradiation stability, MOFs have attracted extensive scientific interests in direct-type X-ray detection.…”

A ratiometric radio-photoluminescence dosimeter based on a radical excimer for X-ray detection

“…17 Moreover, incorporating luminescent inorganic centres with high atomic-number ( Z ) elements in organic–inorganic hybrids has given rise to new scintillators with high detection sensitivity. 18–21 Furthermore, organic–inorganic hybrids can preserve the properties of inorganic and organic fluorophores within a single material, which is pivotal for creating dual-emission materials. Despite this potential, RPL dosimeters based on organic–inorganic hybrids remain very scarce and only started to be reported recently by Wang and colleagues.…”
