Embodiment Construction

[0016] The following description of exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Rather, the scope of the invention is defined by the appended claims. For simplicity, the following examples discuss the terminology and structure of scintillation potassium cryolite compounds with high energy resolution.

[0017] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Thus, appearances of the phrases "in one embodiment," or "in an embodiment" in various places throughout this specification are not necessarily to the same embodiment. Furthermore, particular features, structures, or characteristics may be combined in a...

Abstract

The invention relates to Ce3+ activated mixed halogenide potassium cryolite and a high energy image resolution scintillator. A scintillator composition comprises substrate material and an activating agent. The substrate material comprises at least one alkali metal or thallium, at least one alkali metal different from the alkali metal selected before, at least one lanthanide and at least two halogens. The activating agent is cerium. Besides, the Ce3+ activated mixed halogenide potassium cryolite and the high energy image resolution scintillator further comprised a radiation detector of the scintillator composition and a method used for detecting high energy radiation. The radiation detector constitutes a part of the Ce3+ activated mixed halogenide potassium cryolite and the high energy image resolution scintillator.

Description

technical field [0001] Embodiments of the subject matter disclosed herein relate generally to scintillator compounds, and more particularly, to Ce3+ activated mixed halide potassium cryolites. Background technique [0002] Scintillator materials are commonly used as components of radiation detectors for gamma rays, X-rays, cosmic rays, and particles characterized by energy levels greater than about 1 keV. The scintillator crystals are coupled to light detection means (ie photodetectors). The crystal emits light when photons from a radionuclide source strike the crystal. Photodetectors generate electrical signals that are proportional to the number of light pulses received and the intensity of the light pulses. [0003] Scintillators have been found useful for applications in chemistry, physics, geology, and medicine. Specific examples of these applications include positron emission tomography (PET) devices, well logging for the oil and gas industry, and various digital im...
