利用物理气相沉积法制备了一种简单、低成本的正交相MoO 3晶体，该晶体具有单一的结晶度和较大的尺寸（大于10 mm × 10 mm 2）。结合原子力显微镜、X射线光电子能谱、同步辐射X射线衍射和拉曼光谱等表征技术，从电子结构和物理结构两个方面证实了α-MoO 3晶体的高质量。与以往文献报道相比，我们在此展示了一个相当简化的一步法，只需要MoO 3粉末。最后，对相应的电致变色性能进行了测试，结果表明MoO 3单晶具有较高的透过率和优异的光学性能，有望在纳米传感器、纳米电子学等领域获得更广泛的应用。
By utilizing the convenient physical vapor deposition procedure, a simple and low-cost synthesis route is developed to fabricate high-quality orthorhombic MoO3crystals with single crystallinity and significant size (bigger than 10 mm × 10 mm2). A combined characterization techniques of atomic force microscopy, X-ray photoelectron spectroscopy, synchrotron-based X-ray diffraction and Raman spectroscopy confirm the high quality of α-MoO3crystal from the point view of both electronic and physical structures. Compared to previous reports in literature, we demonstrate herein a rather simplified one-step approach with only the MoO3powder needed. In the end, corresponding electrochromic performance has also been tested which reveals high transmittance and remarkable optical properties which may broadens the potential applications of MoO3single crystal in nanosensors, nanoelectronics and so on.
