Abstract
Metal halide perovskite nanowires have emerged as promising candidates for optoelectronic materials because of their exceptional properties, such as large absorption coefficients and high charge carrier mobility. Conventional methods for synthesizing perovskite nanowires require high temperatures and vacuum conditions. However, we successfully synthesized CsPbBr3 perovskite nanowires under ambient conditions facilitated by ultrasonication. It is especially notable that the incorporation of polystyrene-b-poly(2-vinyl pyridine) (PS-b-P2VP) block copolymers enhanced the solubility of the precursors and effectively suppressed the formation of Cs4PbBr6 intermediate phase, enabling the synthesis of high-purity CsPbBr3 phase nanowires. Moreover, device performance analysis revealed a significant increase in photocurrent under light irradiation in photodetectors. This work highlights the promising potential of perovskite nanowires for next generation optoelectronic applications.
