A ZnO seed layer was formed on the fluorine-doped tin oxide substrate by magnetron sputtering, and then a ZnO nanorod was grown on the ZnO seed layer by a hydrothermal method. Next, we prepared a single-crystal Ag seed layer by magnetron sputtering to form a ZnO@Ag composite heterostructure. Finally, AgPO crystals were grown on the Ag seed layer by a stepwise deposition method to obtain a ZnO@Ag@AgPO ternary heterojunction. The composite heterostructure of the material has super strong hydrophilicity and can be combined with water-soluble pollutants very well. Besides, it has excellent anti-reflection performance, which can absorb light from all angles. When Ag exists in the heterojunction, it can effectively improve the separation of photo-generated electrons and holes, and improve the photoelectric conversion performance. Based on the above characteristics, this nano-heterostructure can be used in the fields of solar cells, sensors, light-emitting devices, and photocatalysis.
通过磁控溅射在氟掺杂氧化锡衬底上形成ZnO籽晶层，然后通过水热法在ZnO籽晶层上生长ZnO纳米棒。接下来，我们通过磁控溅射制备单晶Ag籽晶层以形成ZnO@Ag复合异质结构。最后，通过逐步沉积法在Ag籽晶层上生长AgPO晶体，以获得ZnO@Ag@AgPO三元异质结。该材料的复合异质结构具有超强的亲水性，能够很好地与水溶性污染物结合。此外，它具有优异的抗反射性能，可以从各个角度吸收光线。当Ag存在于异质结中时，它可以有效地改善光生电子和空穴的分离，并提高光电转换性能。基于上述特性，这种纳米异质结构可用于太阳能电池、传感器、发光器件和光催化等领域。
