Description
This study theoretically examines the impact of gamma radiation on a one-dimensional photonic crystal detector, focusing on reflectivity in the visible spectrum using polymer material. This polymer layer consists of polystyrene which is doped by methylene blue. The photonic crystal unit cell consists of alternating layers of silicon dioxide and silicon. We use the characteristic matrix method to analyze the structure's reflectivity and investigate the effects of gamma radiation doses (1000 Rad and 2000 Rad) on resonance. Our results show that parameters like angle of incidence and layer thickness influence the spectral characteristics of the resonance. The detector exhibits a maximum sensitivity of 0.029017nm/Rad. The periodicity used in the proposed design and thickness of the polystyrene layer play a crucial role in creating multiple resonances within the photonic band gap. Our design shows promise for optical applications, including radio medical sensing
