Abstract

X-Ray radiation sensors that work at room temperature are in demand. In this study, a novel, low-cost real-time X-ray radiation sensor based on SnO₂ nanowires (NWs) was designed and tested. Networked SnO₂ NWs were produced via the vapor-liquid-solid technique. X-ray diffraction (XRD), transmission electron microscopy (TEM) and field emission scanning electron microscopy (SEM) analyses were used to explore the crystallinity and morphology of synthesized SnO₂ NWs. The fabricated sensor was exposed to X-rays (80 kV, 0.0-2.00 mA) and the leakage current variations were recorded at room temperature. The SnO₂ NWs sensor showed a high and relatively linear response with respect to the X-ray intensity. The X-ray sensing results show the potential of networked SnO₂ NWs as novel X-ray sensors.
