Development of Organic Metal Halide Hybrids with Short Emission Lifetime for X-Ray Scintillation

Abstract

Scintillator materials, which can emit light under X-ray excitation, have gained a lot of research attention due to their wide range of applications, such as medical imaging via PET scans and X-rays as well as security applications through radiation detectors and X-ray scanners. Recent organic metal halide hybrids, such as tetraphenylphosphonium manganese (II) bromide ((C24H20P)2MnBr4), have been found to be excellent scintillator materials. Their relatively long lifetime is not desirable for many applications. This lifetime can be shorted by the synthesis of a material that replaces the tetraphenylphosphonium (C24H20P+) cation with low band gap cations, such as benzothiazolium-functionalized tetraphenylethene (C37H30NS+) (TPEBe+). The antisolvent diffusion approach is used to synthesize (TPEBe)2MnBr4, which is found to exhibit orange emission with a short lifetime, thus exhibiting more useful properties for scintillator applications.
