Hybrid detectors for high-energy radiation based on borosilicate glass scintillator doped with Gd3+covered by photosensitive TiO2 layer
Original language description
Vacuum ultraviolet (VUV) radiation, ranging from 100 to 200 nm (6.2-12.4 eV), is essential for applications in photonics, plasma diagnostics, and high-energy radiation monitoring. This study presents a hybrid VUV detector composed of a Gd2O3-doped borosilicate glass scintillator coated with a 250 nm titanium dioxide (TiO2) film. Borosilicate glass was selected for its high thermal stability, chemical durability, and rare-earth compatibility. The TiO2 a band gap near 3.2 eV layer, deposited via DC magnetron sputtering, acts as a photoconductive material that directly converts the 311 nm, approximately 3.99 eV photoluminescence emission from Gd3+ into an electrical signal, eliminating the need for a separate photodetector. Substrate heating during deposition and post-deposition annealing significantly improved the crystallinity of the TiO2 layer, enhancing photosensitivity without degrading the luminescence of the underlying scintillator. The selected film thickness ensures good photon absorption and surface uniformity while avoiding charge carrier recombination losses. Furthermore, The system demonstrates successful detection of 172 nm VUV radiation via direct luminescence to current conversion. This hybrid device provides a compact, integrated for high-energy radiation detection, with potential applications in dosimetry and future VUV or x-ray optoelectronic systems.
