Quasi Periodic Photonic Crystal as Gamma Detector Using Poly Nanocomposite and Porous Silicon / F.A.Sayed, Z.A.Zaky, V.D.Zhaketov, [a.o.]. – Text : electronic // Scientific Reports. – 2025. – No. 15. – P. 18451. – URL: https://doi.org/10.1038/s41598-025-02910-2. – Bibliogr.: 75.
This research investigates the design and performance of quasi-periodic photonic crystals built using Thue-Morse sequences for gamma dosimetry applications. The structures were made of aluminum oxide and porous silicon infused with a poly(ethylene oxide) nanocomposite. The transmittance spectra of these crystals are heavily dependent on their structural evolution, with higher-generation structures exhibiting greater localization of defect modes. The study combines experimental data fitting with theoretical calculations to validate the optical behavior of the developed structures. These calculations were performed using the transfer matrix method over a wavelength range of 500–800 nm. Each structure’s sensitivity and quality factor were evaluated in two radiation ranges—0–100 Gy and 100–200 Gy—to determine their potential as gamma dosimeters. The results demonstrate that the proposed structures are highly effective for dosimetry applications. They achieve an optimal balance between sensitivity (0.55 nm/Gy and 0.5 nm/Gy) and sharp defect modes, with quality factors of 1715.9 and 473, respectively. These findings suggest that Thue-Morse sequence-based photonic crystals can serve as highly tunable and efficient gamma radiation sensors.
