Substoichiometric tungsten oxide (WO_x, 2 < x < 3) nanomaterials are important nanoscale semiconductor materials with broad applications in optoelectronic devices; however a controllable modification of their physical properties remains challenging task. Here, we report an alternative green synthesis of hybrid nanostructures composed by WO_x and ZnWO₄ phases in ethanol via a solvothermal process using ZnO and WCl₆ as the precursors. The results indicate that the formation of ZnWO₄ leads to the structural conversion of WO_x from nanorods to nanoparticles due to the effect of ZnWO₄ on the side growth of WO_x nanostructures. Moreover, the surface morphology tailored by ZnWO₄ and crystalline phase transformation induce different photoluminescence (PL) emission from pure WO_x nanostructures and WO_x/ZnWO₄ hybrid nanostructures due to the increased number of oxygen vacancies.

亚化学计量的氧化钨（WO _x，2 <  x  <3）纳米材料是重要的纳米级半导体材料，在光电子器件中具有广泛的应用。然而，对其物理性能的可控改变仍然是一项艰巨的任务。在这里，我们报告了通过溶剂热过程，使用ZnO和WCl ₆作为前体，在乙醇中由WO _x和ZnWO ₄相组成的杂化纳米结构的另一种绿色合成。结果表明，ZnWO的形成_4所导致的WO结构变换_X从纳米棒的纳米颗粒由于ZnWO的效果₄上的WO侧生长_x纳米结构。此外，由于氧空位数目的增加，由ZnWO ₄和结晶相转变量身定制的表面形态诱导了来自纯WO _x纳米结构和WO _x / ZnWO ₄杂化纳米结构的不同光致发光（PL）发射。
