| contents | The evolution of X-ray detection technology has significantly enhanced sensitivity and spatial resolution in non-destructive imaging of internal structure. However, the problem of low luminescence and transparency of scintillator materials restricts imaging with lower radiation doses and thicker materials. Here, we propose a two-dimensional photonic scintillator for single crystal and demonstrate that the optical guiding effect emerging from the structure reduces luminescence leakage and increases the signal intensity by around a factor of 2 from 200 to 450 kV. This approach has the potential to enhance the output rate by an order of magnitude. The photonic structure features a fine array pitch and large-scale detection area with fast fabrication time. Our scheme paves the way for high sensitivity X-ray imaging. |
