Composition of Plastic Scintillator

（1）plastic matrix

The plastic matrix is a crucial component of plastic scintillators, accounting for over 97% of the material and having a significant impact on its physical and chemical properties. Aromatic compounds are the most common type of matrix used in plastic scintillators due to their necessary role in fluorescence absorption and emission processes. These aromatic matrices can be categorized into polystyrene, polyester, polysiloxane, polyepoxy resin, and polyvinyl alcohol. Polystyrene (PST) and polyvinyl toluene (PVT) are among the earliest matrices used with high detection efficiency. Non-aromatic matrices such as polymethyl methacrylate (PMMA), composed of carbon-oxygen double bonds and ester-bonded oxygen atoms, have weaker fluorescence intensity but better transparency than polystyrene. When used in combination with an aromatic solvent at a certain proportion, PMMA can improve both mechanical properties and transparency.

（2）scintillating material

The luminescence efficiency of the matrix in the plastic scintillator is very low, and when the scintillator is subjected to nuclear radiation (α, β, γ rays, etc.) or high-energy particles, if only the plastic matrix is used, most of the electron excitation energy will be released in non-radiative form and affect the detection efficiency. At the same time, the emission spectrum of the plastic matrix is primarily in the range of 300-350 nm. However, this emission wavelength is too short to match with ordinary photomultiplier tubes which have a low quantum efficiency in this band. Therefore, it becomes necessary to add scintillation materials to increase light yield in plastic scintillators. Scintillation materials can be divided into primary scintillation materials and wave shifting agents that should possess good solubility and temperature resistance (able to withstand temperatures between 100-170 °C), chemical stability (must coexist with all other components without being vulnerable to free radical attack during polymerization process), light resistance and low cost. Primary scintillation material refers to an aromatic compound which serves as the main luminous material with a mass fraction usually ranging from 0.3-4% and fluorescence emission wavelength between 350-400 nm. On the other hand, wave shifting agents are responsible for shifting maximum luminous wavelength towards a range that matches photomultiplier tubes; their mass fraction is lower than that of primary scintillation substance typically falling within 0.001-0.1wt %. Additionally, ultraviolet absorption spectrum of primary scintillation material should coincide with fluorescence spectrum of plastic matrix while ultraviolet absorption spectrum of wave shifting agent should match fluorescence spectrum of primary scintillation material so as to minimize energy loss and improve detection efficiency.

How Does A Plastic Scintillator Work?

A plastic scintillator works by converting ionizing radiation into visible light, which can then be detected and measured. When a plastic scintillator is exposed to ionizing radiation, electrons within the scintillating plastic become excited and move from their locked position in the valence band to the conduction band, where they are free to move around. This movement leaves an associated hole behind in the valence band. As the excited electrons return to their original state, they release energy in the form of photons, producing visible light.

Plastic scintillator materials are valued for their fast response time, durability, and ease of fabrication. Key plastic scintillator properties include high light output, good transparency, and the ability to be shaped into various forms for different applications.
