Abstract

This study explores the development of a hybrid scintillation system for vacuum ultraviolet (VUV) radiation detection, combining cerium-doped yttrium‑aluminum perovskite (Ce:YAP) with a photoconductive titanium dioxide (TiO₂) layer. This system enables direct conversion of scintillation luminescence into electrical signals, eliminating the need for a standalone photodetector. The effects of thermal treatment, including substrate heating during TiO₂ deposition and post-deposition annealing, on the hybrid system's properties were investigated. The results show that thermal processing enhances TiO₂ crystallinity, improves the luminescence properties of Ce:YAP, and significantly increases the photosensitivity of the hybrid scintillator. This research highlights the potential of hybrid approaches for radiation detection in applications spanning science, medicine, and industry.

在混合Ce:YAP-TiO 2闪烁体中通过发光-电信号转换直接检测辐射

本研究探索了一种用于真空紫外（VUV）辐射检测的混合闪烁系统的开发，该系统将掺铈钇铝钙钛矿（Ce:YAP）与光导二氧化钛（TiO₂）层结合在一起。该系统能够将闪烁发光直接转换为电信号，从而消除了对独立光电探测器的需求。研究了tio2沉积过程中衬底加热和沉积后退火等热处理对杂化体系性能的影响。结果表明，热处理提高了tio2结晶度，改善了Ce:YAP的发光性能，显著提高了杂化闪烁体的光敏性。这项研究突出了辐射探测的混合方法在科学、医学和工业应用中的潜力。

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
