Amine‑Salt‑Assisted Solution Crystallization of Inorganic Perovskite Single Crystals for High‑Performance X‑Ray Detection (IMAGE)
Caption
- An amine-salt-assisted solution crystallization strategy is developed to grow high-quality CsPbCl3 single crystals (SCs) with a size as large as 15 mm, the SCs exhibit a high carrier mobility-lifetime product, low trap density, and large resistivity.
- The CsPbCl3 SC X-ray detector achieved a high detection sensitivity of 76,624 μC Gy-1 cm-2 and a low detection limit of 47.9 nGy s-1, a short response time of 700 μs, therefore realized high contrast X-ray imaging.
