“…Further, similar results have been obtained for plastic scintillators loaded with Pr-doped LaPO 4 136) or CeF 3 . 137,138) These results strongly suggest that electronic excitation in the nanoparticles transfer to the host polymer or fluorescent molecules. If the energy transfer could be fully exploited, the scintillation light yield would not decrease with loading concentration of the nanoparticles.…”

“…Our group have developed polystyrene-based scintillators with 1,1,2,2-tetraphenylethylene (TPE) as the AIE molecule. 54) Figures 9 and 10 present the quantum yield of photoluminescence and the pulse-height spectra under irradiation of 662 keV gamma rays from 137 Cs as functions of TPE concentration, respectively. The quantum yield of photoluminescence did not decrease with the TPE concentration, which is contrary to the case of general fluorescent molecules.…”

Recent development of organic scintillators is reviewed from the viewpoint of materials science. Design and crystal growth of organic crystalline scintillators, use of novel solvents and solutes in liquid scintillators, and development of plastic scintillators based on novel polymer hosts or novel fluorescent molecules are introduced. Additionally, development of loaded liquid or plastic scintillators is reviewed on the basis of two approaches of loading: molecules or nanoparticles. A disadvantage of organic scintillators has been their low scintillation light yields. Hence, materials design for improving scintillation light yields is introduced in detail with description on related excited state dynamics. Finally, future prospect for the improvement of scintillation light yield is briefly given.

“…Strategies such as surface modification pretreatment and in situ polymerization are preferred to be adopted, rather than direct mixing. Guided by the above principle, various types of inorganic crystals, including halide families such as BaF 2 , [13,14] CeF 3 , [15][16][17] and CsI; [13,18] oxide family such as Gd 2 O 3 , [19][20][21] Lu 2 SiO 5 (LSO), [22] and LaPO 4 ; [23] and quantum dots such as ZnS, [24] ZnO, [25] CdSe, [26] and CdTe, [27] have been selected to be integrated into polymer matrix to construct particle-polymer structured scintillators. Depending on their functions in composites, the incorporated particles can be mainly divided into two groups: emitting particles (Figure 2a) and nonemitting particles (Figure 2b).…”

“…In a follow‐up work in 2018, a CeF 3 /PS structured scintillator was synthesized with a loading proportion of 40 wt%. [ 17 ] Rational control of the size of the incorporated particles at 12 nm can help maximize the energy transfer efficiency, resulting in a 16‐fold enhancement of radioluminescence compared with that of pure PS. Particle–polymer structured scintillator via incorporation of nonemitting particles with high neutron cross‐section in polymer matrix was also developed for neutron detection.…”

Scintillators, which can convert high‐energy ionizing radiation into visible light, have been serving as the core component in radiation detectors for more than a century of history. To address the increasing application demands along with the concern on nuclear security, various strategies have been proposed to develop a next‐generation scintillator with a high performance in past decades, among which the novel approach via structure control has received great interest recently due to its high feasibility and efficiency. Herein, the concept of “structure engineering” is proposed for the exploration of this type of scintillators. Via internal or external structure design with size ranging from micro size to macro size, this promising strategy cannot only improve scintillator performance, typically radiation stopping power and light yield, but also extend its functionality for specific applications such as radiation imaging and therapy, opening up a new range of material candidates. The research and development of various types of structured scintillators are reviewed. The current state‐of‐the‐art progresses on structure design, fabrication techniques, and the corresponding applications are discussed. Furthermore, an outlook focusing on the current challenges and future development is proposed.
