Abstract 1, 3, 5-triphenylbenzene (TPB) single crystal (length 100 mm and diameter 10 mm) has been successfully grown for the first time by the modified vertical Bridgman technique (VBT). This method is developed for the growth of crystals (changing the translation system using gear setup), with enhanced quality. Physical, optical and scintillation properties such as crystalline nature, thermal stability, transmittance, radioluminescence and lifetime were investigated. The polished TPB sample has a good transmission (80%) in the wavelength range between 300 and 1500 nm. The thermal properties of the grown crystal were analyzed by thermogravimetric and differential thermal analyses. Measurements of the refractive index of TPB crystal were made using the prism coupling method at five different wavelengths in the range between 407 and 1551 nm. Birefringence study reveals that the grown crystal has good optical homogeneity. Scintillation properties such as radioluminescence using Sr-90 as a source and decay time were also investigated.

1, 3, 5-三苯苯单晶的改进垂直布里奇曼法生长及其闪烁应用表征

摘要 1, 3, 5-三苯基苯(TPB) 单晶(长100 mm, 直径10 mm) 通过改良的垂直布里奇曼技术(VBT) 首次成功生长。这种方法是为晶体生长（使用齿轮设置改变平移系统）而开发的，具有更高的质量。研究了物理、光学和闪烁特性，例如结晶性质、热稳定性、透射率、辐射发光和寿命。抛光的 TPB 样品在 300 到 1500 nm 的波长范围内具有良好的透射率 (80%)。通过热重分析和差热分析来分析生长晶体的热性能。使用棱镜耦合方法在 407 至 1551 nm 范围内的五种不同波长下测量 TPB 晶体的折射率。双折射研究表明，生长的晶体具有良好的光学均匀性。还研究了闪烁特性，例如使用 Sr-90 作为源的辐射发光和衰减时间。
