Low-dose real-time X-ray imaging with nontoxic double perovskite scintillators.

ABSTRACT: X-rays are widely used in probing inside information nondestructively, enabling broad applications in the medical radiography and electronic industries. X-ray imaging based on emerging lead halide perovskite scintillators has received extensive attention recently. However, the strong self-absorption, relatively low light yield and lead toxicity of these perovskites restrict their practical applications. Here, we report a series of nontoxic double-perovskite scintillators of Cs₂Ag_0.6Na_0.4In_1-yBi_yCl₆. By controlling the content of the heavy atom Bi³⁺, the X-ray absorption coefficient, radiative emission efficiency, light yield and light decay were manipulated to maximise the scintillator performance. A light yield o
