  • Patent number: 11513242
    Abstract: 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. Radiation detectors, as described herein, may have beneficial properties, including enhanced charge collection and long-term stability.

  • Publication number: 20170279001
    Abstract: A detector for detecting radiation is generally described. The detector can comprise at least one ionic semiconductor material. For example, the ionic semiconductor material comprises a thallium halide and/or an indium halide. Electrical contacts are formed on the semiconductor material to provide a voltage to the detector during use. At least one of the electrical contacts may comprise a liquid that contains ions. In some instances, at least one electrical contact comprises a metal, such as Cr, Ti, W, Mo, or Pb. In some embodiments, the detector comprises both an electrical contact comprising liquid comprising ions and an electrical contact comprising a metal selected from a group consisting of Cr, Ti, W, Mo, and Pb. Detectors for detecting radiation, as described herein, may have beneficial properties.
