초록

Organic scintillators have emerged as promising candidates in radiation detection due to their superior response times and versatile fabrication methods. However, several challenges, such as low fluorescence yield, limited stability, and low energy resolution, limit their use. This review comprehensively examines recent research efforts that address these limitations through molecular engineering and innovative material design. It discusses various classes of novel materials, including crystalline, liquid, plastic, and hybrid scintillators, along with advanced manufacturing techniques and mechanisms. By incorporating efficient luminophores, high Z elements, innovative solvents, and nanocomposites, researchers aim to enhance the performance of organic scintillators to make them comparable in effectiveness to their inorganic counterparts. These fabrication advancements are explored in detail. With a focus on improving fluorescence yield, the paper also reviews the reliance of organic scintillators on the thermally activated delayed fluorescence mechanism, which makes triplet excitons available for scintillation. The application of machine learning algorithms to enhance pulse shape discrimination properties is also discussed thoroughly. Finally, future prospects for organic scintillators in efficient radiation detection are highlighted, offering insights into their potential for next-generation applications. © 2026 Elsevier Ltd
