Abstract
Chemically-modified silicone-based matrices for use in radiation detection. The base matrix is capable of multi-modal particle detection via pulse shape discrimination (PSD), relying in differences in the interaction mechanics between various types of radiation and the matrix itself to produce light with characteristic properties dependent on the incident particle type and energy. The materials, radiation detection devices using the materials, and methods of using the materials as radiation detectors.
