Abstract
In this work, Cs6Cu3AgBr10 perovskite was synthesized by hot-injection method. Through a series of structural and morphological characterization techniques, it was shown that the synthesized Cs6Cu3AgBr10 perovskite has high purity and good crystal structure. Theoretical calculation shows that Cs6Cu3AgBr10 perovskite material has a direct band gap structure, which is advantageous to the separation and transmission of photogenerated carriers, and thus improve the photoelectric conversion efficiency of the material. In addition, the flexible film made based on vacuum filtration has good flexibility, uniformity, and a smooth and dense particulate layer. Imaging systems based on this membrane can achieve a high resolution of more than 19.35 lp/mm, which is one of the highest values reported in the literature. These studies show great potential for practical X-ray imaging applications.
期刊介绍:
The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid.
We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
