Scintillator materials, as well as related systems, and methods of detection using the same, are described herein. The scintillator material composition may comprise a Tl-based scintillator material. For example, the composition may comprise a thallium-based halide. Such materials have been shown to have particularly attractive scintillation properties and may be used in a variety of applications for detection radiation.

Thallium-based scintillator materials

Scintillator compositions comprising lithium, an alkaline earth metal, a halide, and optionally a dopant, and related systems and methods for detecting radiation are disclosed.

Scintillator materials comprising lithium, an alkaline earth metal, and a halide

Systems and methods for detecting radiation are generally described. The radiation detector comprises at least one semiconductor material, such as a thallium halide, that provides an electrical signal and optical signal upon exposure to a source of radiation. The electrical signal and optical signal may both be measured to detect the radiation.

Wide bandgap semiconductor radiation detectors

A radiation detector is generally described. The detector can comprise a thallium halide (e.g., TlBr) and/or an indium halide. The thallium halide and/or indium halide can be doped with a dopant or a mixture of dopants. The dopant can comprise an alkaline earth metal element, a lanthanide element, and/or an element with an oxidation state of +2. Non-limiting examples of suitable dopants include Ba, Sr, Ca, Mg, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and/or Yb.
