Excitation-Wavelength-Dependent Emission Behavior in (NH₄)₂SnCl₆ via Sb³⁺ Dopant.

ABSTRACT: With high photoluminescence efficiency and a simple solution synthesis method, lead halide perovskites are expected to be a promising material for display and illumination. However, the toxicity and environmental sensitivity of lead hinder its potential applications. Here, we introduced Sb³⁺ ions into the lead-free perovskites derivative (NH₄)₂SnCl₆ via a doping strategy. For the first time we synthesis the excitation-dependent perovskite with dynamically tunable fluorescence from yellow to near-infrared (NIR) emission by varying the UV excitation from 360 to 390 nm at room temperature. The DFT calculations are highly consistent no matter whether the coordination number of Sb³⁺ is 5 or 6. In contrasting to the early report of Sb triple
