摘要

航空材料是一类在各种应用中越来越有吸引力的材料。其中,气相锌盐是通过在由微四面体网络组成的牺牲性氧化锌模板上进行氢化物气相外延而制备的,并已被提出用于微流体应用。本文提出了一种具有成本效益的技术方法,以 Sn2S3 晶体和 ZnO 微网状物网络为前驱体,利用物理气相传输技术制造气态 ZnS。我们用扫描电子显微镜(SEM)研究了所制材料的形态,并分别用 X 射线衍射(XRD)分析和光致发光(PL)光谱评估了其结晶和光学质量。我们展示了通过工艺流程的长短来控制所制备气凝胶的成分和结晶相含量的可能性。从光致发光分析中推导出了气凝胶材料 ZnS 骨架中的深能级和电子跃迁方案,这表明所制备的气凝胶是光催化和传感器应用的潜在候选材料。

Aero-ZnS prepared by physical vapor transport on three-dimensional networks of sacrificial ZnO microtetrapods.

Aeromaterials represent a class of increasingly attractive materials for various applications. Among them, aero-ZnS has been produced by hydride vapor phase epitaxy on sacrificial ZnO templates consisting of networks of microtetrapods and has been proposed for microfluidic applications. In this paper, a cost-effective technological approach is proposed for the fabrication of aero-ZnS by using physical vapor transport with Sn2S3 crystals and networks of ZnO microtetrapods as precursors. The morphology of the produced material is investigated by scanning electron microscopy (SEM), while its crystalline and optical qualities are assessed by X-ray diffraction (XRD) analysis and photoluminescence (PL) spectroscopy, respectively. We demonstrate possibilities for controlling the composition and the crystallographic phase content of the prepared aerogels by the duration of the technological procedure. A scheme of deep energy levels and electronic transitions in the ZnS skeleton of the aeromaterial was deduced from the PL analysis, suggesting that the produced aerogel is a potential candidate for photocatalytic and sensor applications.
