Ga2O3 has been considered as one of the most suitable materials for x-ray detection, but its detection performance is still at a low level due to limitation quality and absorbance, especially hard x-ray. In this work, effects growth temperature miscut angle sapphire substrate on crystal thin films were investigated based MOCVD technique. It was found that mode transformed from island step-flow using substrates increasing temperature, which accompanied by improvement reduction density trapped states. with optimal finally prepared 4° 900 °C. The detector film shows good response sensitivity 3.72 × 105μC·Gyair−1·cm−2. Furthermore, impacts trap in depth, mechanism photoconductive gain thin-film analyzed.

Abstract Nanostructured scintillators, renowned for their exceptional miniaturization and portability, are typically designed with homogeneous dopant ion concentration profiles. While these profiles facilitate consistent optical properties, they may pose challenges in terms of compromising light emission intensity overall scintillation efficiency. A pressing issue the field X‐ray flat‐panel minidetectors is lack specific innovative strategies to significantly enhance radioluminescence capabilities, which has hindered further advancements. This research showcases an efficacious strategy synthesizing ligand‐exchange‐passivated mixed‐halide double perovskite nanocrystals (NCs) tailored remarkable capabilities. The composition fine‐tuned via anion exchange between Bi 3+ Tb ‐doped Cs 2 AgInCl 6 NCs potassium bromide (KBr). Additionally, initial oleic acid ligands substituted 1‐dodecanethiol (1‐DT), effectively compensating inherent halogen vacancies mitigating halide migration. underlying passivation mechanism elucidated through a comprehensive approach that combined spectroscopic experiments theoretical calculations. Consequently, fabricated transparent scintillator films, incorporating synthesized NCs, exhibit high yield ≈20 952 photons MeV −1 , sensitive detection limit 207.5 nGy air s spatial resolution 8.1 lp mm unparalleled stability under prolonged irradiation.
