In this work, tin oxide (SnO) nanoarrays (NAs) with a novel morphology were fabricated by a hydrothermal method. Each SnO nanorod (NR) consisted of a bunch of nearly ten primary NRs with a width of 4-7 nm. On this basis, gold (Au) nanoparticles (NPs) were used to induce the growth of smaller and more orderly SnO NAs. The prepared ultraviolet (UV) detectors based on SnO NAs have high responsivity and high external quantum efficiency (EQE) under 20 μW cm UV light with only 1 V external bias voltage.
在本工作中，通过水热法制备了具有新颖形貌的氧化锡（SnO）纳米阵列（NAs）。每个SnO纳米棒（NR）由一束近十根宽度为4 - 7 nm的初级NR组成。在此基础上，使用金（Au）纳米颗粒（NPs）诱导生长更小且更有序的SnO NAs。所制备的基于SnO NAs的紫外（UV）探测器在仅1 V外部偏置电压下，于20 μW/cm²的紫外光照射下具有高响应度和高外部量子效率（EQE）。
