We report a versatile hybrid device consisting of one-dimensional ZnS and Te-doped ZnS (ZnS:Te) nanowires (NWs) upon two-dimensional multilayer graphene films (MGFs). Single-crystalline ZnS and ZnS:Te NWs were grown directly on a MGF without a catalyst, and exhibited blue-green and blue emission peaks of ∼ 503 and ∼ 440 nm. A field emission light emitter using ZnS:Te NWs on a MGF was demonstrated, and it indicates excellent contact properties between the NWs and MGFs. The resulting hybrid devices are promising candidates for potential applications as building blocks for the development of highly functional and efficient electroluminescent devices and field-emitting devices including flexible and/or transparent display devices.
我们报告了一种多功能混合器件，它由一维的 ZnS 和掺 Te 的 ZnS（ZnS:Te）纳米线（NWs）组成，基底为二维多层石墨烯薄膜（MGFs）。单晶 ZnS 和 ZnS:Te NWs 无需催化剂即可直接在 MGF 上生长，表现出约为 503nm 和 440nm 的蓝绿色和蓝色发射峰。我们展示了一种基于 MGF 上的 ZnS:Te NWs 的场发射光源，这表明 NWs 和 MGFs 之间具有优异的接触性能。这种混合器件有望成为用于开发高功能和高效电致发光器件和场发射器件的构建块的有前途的候选材料，其中包括柔性和/或透明显示器件。
