Ultra-Thin Oxide Membrane Encapsulation for Perovskite X-Ray Detectors

Objective

Metal-halide perovskites are among the most promising materials for next-generation X-ray detectors, combining high sensitivity, fast response, and low-cost manufacturing potential. They could enable faster medical imaging, lower patient radiation doses, and more efficient industrial inspection. However, their widespread use is blocked by a major limitation: intrinsic instability. Moisture, heat, electric fields, and ionizing radiation rapidly degrade perovskites, causing signal loss and short device lifetime. SEAL-X-RA addresses this bottleneck with a radically new encapsulation strategy based on ultra-thin membranes. These membranes act as conformal, radiation-compatible barriers that protect perovskite scintillators from environmental and radiation-induced degradation without compromising optical performance. Preliminary results already show more than a tenfold improvement in radiation tolerance. Beyond X-ray detection, SEAL-X-RA introduces a platform technology for protecting unstable high-performance materials in harsh environments, with potential applications in optoelectronics, photovoltaics, and space technologies.
