Abstract:
We report the preparation of flexible scintillation films based on Ag6N6S12C54H48 (Ag-R-4PTT) clusters formed by in-situ crystallization within a polymer matrix. The Ag-R-4PTT clusters exhibit thermally activated delayed fluorescence with a high photoluminescence quantum yield of 93.1%. Controlled crystallization yields microcrystalline clusters in poly(vinylpyrrolidone)/thermoplastic polyurethane matrices with excellent radioluminescence performance and high structural stability, leading to a light yield of 33 400 photons MeV-1 and an X-ray detection limit down to 231 nGyair s-1. The scintillation films retain high mechanical flexibility, optical transmittance, and water-resistance, achieving a spatial resolution of 21 lp mm-1 for X-ray imaging. This study introduces a general strategy to stabilize Ag clusters via coordination engineering as well as in-situ crystallization, offering a promising platform for flexible radiation detection and high-resolution imaging.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
