In Research Article (e25694), Ming-Gang Ju, Kui Zhao, Yi Zhang, and co-workers pioneer a Sb/Bi solid solution strategy to design a lead-free halide ferroelectric with the lowest bandgap. They innovatively employ isothermal evaporation of green solvent γ-valerolactone to grow single crystals, achieving record-breaking X-ray sensitivity. This breakthrough establishes a new benchmark for sustainable synthesis, paving the way for next-generation eco-friendly X-ray detection.
