biostudies-literatureUnknown6Zhao XLead halide perovskite nanocrystals have recently demonstrated great potential as x-ray scintillators, yet they still suffer toxicity issues, inferior light yield (LY) caused by severe self-absorption. Nontoxic bivalent europium ions (Eu²⁺) with intrinsically efficient and self-absorption-free <i>d-f</i> transition are a prospective replacement for the toxic Pb²⁺. Here, we demonstrated solution-processed organic-inorganic hybrid halide BA₁₀EuI₁₂ (BA denotes C₄H₉NH₄⁺) single crystals for the first time.
