Abstract
Scintillation compositions comprising one or more different types of quantum dots dispersed in a polymer matrix material, the quantum dots having a core-shell structure, and optionally a neutron-capturing isotope. Hydrogels comprising the quantum dots and optional neutron-capturing isotope in a polymerized matrix are also disclosed, as are related detection systems and methods.

A scintillation composition comprising one or more different types of quantum dots dispersed in a polymer matrix material, the quantum dots comprising a core-shell structure.
A hydrogel comprising a polymerized matrix material and one or more different types of quantum dots in the polymer matrix material.
A detection system comprising:
- an enclosure, at least one photomultiplier tube in the enclosure, and a hydrogel in proximity to the at least one photomultiplier tube, the hydrogel of the detection system configured to detect at least one of neutron radiation and gamma radiation, and the hydrogel comprising:
- one or more different types of quantum dots and a polymerized matrix material.
A method of detecting radiation emitting from an article, comprising:
- positioning an article emitting one or more of neutron radiation and gamma radiation proximal to a hydrogel in a detection system, the hydrogel comprising a polymerized matrix material comprising one or more different types of quantum dots and an optional neutron-capturing isotope;
- and
- detecting the one or more of the neutron radiation and gamma radiation.
