The development of high-speed imaging technology requires ultrafast scintillators. ZnO is an excellent scintillator whose near-band-edge (NBE) radiation attenuation can reach subnanosecond levels. Homogeneous and unique double-layered ZnO:Sc microcrystals (1% doping) were prepared by adding polyvinylpyrrolidone during a hydrothermal reaction. growth process double-layer the effects Sc doping concentration on morphology studied. tended to nucleate into twins in weakly basic hexamethylenetetramine. c-axis was inhibited doping, pyramid accordance with Burton–Cabrera–Frank model (002) plane, according spiral dislocation. Sheet obtained under high-concentration doping. After hydrogen annealing, NBE intensity 0.5%-doped higher than that ZnO, mainly owing inhibition defect luminescence sheet morphology, which reduced self-absorption ZnO:Sc. decay time after annealing ultraviolet excitation less 1 ns. Combining annealed polydimethylsiloxane form flexible composite film enables scintillation screen be used for X-ray detection spatial resolution up 16 lp/mm.

Zinc oxide (ZnO) has emerged as one of the most promising candidates for mass-producing cost-efficient optoelectronic devices. This is primarily because it can be synthesized in high-quality nanostructures on a wide range substrates through relatively simple chemical methods. However, producing p-type ZnO, regardless chosen method, remains an open and controversial issue. In this work, Li-doped ZnO varying Li-cocnentration were produced via two-step hydrothermal growth synthesis in-depth analysis based with Field Emission Scanning Electron Microscopy (FE-SEM), X-ray diffraction (XRD), Raman Spectroscopy, Extended X-Ray Absorption Fine Structure (EXAFS) temperature-dependent Photoluminescence (PL) was carried out effort to gain insights into Li-incorporation mechanisms. The findings indicated strong interplay between native defects responsible inherent n-type character material Li incorporation. It suggested that hinders successful conversion nanorods when employing approach essential identify precise conditions necessary genuine incorporation Zn substitutional.
