Embodiments incorporate a method and apparatus for detection of radiation. Embodiments detect fast and/or thermal neutrons. Embodiments detect neutrons in high backgrounds of gamma rays. Embodiments can have high sensitivity and/or high gamma discrimination. Embodiments include a given single material that detects fast neutrons and simultaneously detect gamma rays with moderate energy resolution. Embodiments utilize liquid, viscous liquid, gel, and/or solid scintillating materials. Embodiments incorporate a scintillating matrix, such as a liquid, having a highly polar matrix, such as a liquid solvent, dissolved dyes, and a high concentration of a dissolved organo metallic compound. The use of a single material for a large area detector of fast neutrons and gamma rays can provide material and cost benefits.

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.

Embodiments of the invention relate to microfabrication of three dimensional polymeric structures incorporating a large number of identical elements each having one or more materials. In specific embodiments, the structures are large area fiber optic plates and associated structures, wherein the fibers are precisely located relative to each other and can serve as optical readout, such as optical readout for high density microarrays of biomaterial and other chemicals or pharmaceuticals. A three-dimensional fiber optic plate can be fabricated by a lithographic process in which a 2D solid slice is produced by exposing a 2D layer of photocurable liquid to ultraviolet light. The cured layer is lowered and the process is repeated to build the plate layer by layer.
