  • Patent number: 9321957
    Abstract: A radiation detector can include a solid organic/plastic scintillator that enables neutron and gamma interactions to be readily distinguished via pulse-shape discrimination. Embodiments make use of a scintillator including a polymer matrix with a dispersed scintillation material exhibiting thermally activated delayed fluorescence. The scintillation material can include an organic luminescent material that is free of heavy metals and in which excited triplet states are efficiently promoted into excited singlet states by thermal energy, the excited singlet states then generating a delayed fluorescence when decaying to ground state. As a result, the scintillation material, when exposed to ionizing radiation, can produce a combination of prompt and delayed fluorescence sufficient to enable neutron and gamma interactions to be readily distinguished via pulse-shape discrimination techniques.

  • Patent number: 9004131
    Abstract: A method and a system for producing a change in a medium disposed in an artificial container. The method places in a vicinity of the medium at least one of a plasmonics agent and an energy modulation agent. The method applies an initiation energy through the artificial container to the medium. The initiation energy interacts with the plasmonics agent or the energy modulation agent to directly or indirectly produce the change in the medium. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the plasmonics agent or the energy modulation agent.

  • Patent number: 8993968
    Abstract: Embodiments of the invention provide a scintillator material, a scintillator system, and/or a method of detecting incident radiation using a scintillator material, or scintillator system, comprising a polymer material that comprises chromophores. Additional embodiments provide a scintillator material, scintillator system, and/or a method of detecting incident radiation using a scintillator material, or scintillator system, comprising a polymer material having one, two, three, or more, organic dyes dissolved therein wherein the polymer material having the one, two, three, or more dyes dissolved therein comprises chromophores. At least one of the dyes, termed the base dye, has a concentration in the range 0.5 to 3.5 mol/L. In a specific embodiment, the base dye has a concentration in the range 1.0 to 3.0 mol/L. This base dye concentration is high enough to achieve a substantial triplet-triplet state annihilation rate despite the negligible diffusion of the dye in the rigid polymer matrix.
