As a scintillating material, colloidal quantum dots (cQDs) are proving to be a promising alternative to traditional organic fluorophores used for radiation detection. By varying the size and composition of the cQDs, their physical and optical properties can be controlled. Furthermore, through appropriate functionalization of the cQD surface, they can be easily integrated within a variety of matrices, making them an appealing choice for the development of a new generation of scintillation dosimeters. In this article, three types of cQDs are incorporated in polystyrene to produce nanocomposite optical fibers, and their response to 6-MV X-rays is investigated. All fibers show a linear response with delivered dose, minimal dependence on the linac dose rate, and for the case of the CdSe/CdS cQD-doped fiber, a reasonable resistance to radiation-induced signal degradation.

用于闪烁剂量测定的胶体量子点掺杂光纤

作为一种闪烁材料，胶体量子点 (cQD) 被证明是用于辐射检测的传统有机荧光团的有前途的替代品。通过改变 cQD 的大小和组成，可以控制它们的物理和光学特性。此外，通过 cQD 表面的适当功能化，它们可以轻松集成到各种基质中，使其成为开发新一代闪烁剂量计的有吸引力的选择。在本文中，将三种类型的 cQD 结合到聚苯乙烯中以生产纳米复合光纤，并研究了它们对 6-MV X 射线的响应。所有光纤都显示出对输送剂量的线性响应，对直线加速器剂量率的依赖性最小，对于 CdSe/CdS cQD 掺杂光纤，
