Emissive Chalcogenide Perovskite Nanowires
Efficient and stable one-dimensional semiconductor nanowires are critical for the development of next-generation on-chip optoelectronics. Here, we report a synthetic approach to produce high-quality nanowires based on chalcogenide perovskite via a vapor phase reaction inside a sealed ampule. An epitaxial vapor-phase growth mechanism is proposed. The nanowires are shown to be single crystalline and highly structurally stable, with a preferential growth along the [010] direction. Red and green photoluminescence (PL) is observed from BaZrS<sub>3</sub> and SrHfS<sub>3</sub> nanowires, respectively, and the emission is shown to be tunable with varying compositions. PL lifetime is measured by fitting the decay curve with a biexponential model. The longer radiative recombination lifetime component is on the time scale of nanoseconds, indicating good nanowire sample quality with a promising potential for optoelectronic applications.
