- 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. © 2010 IOP Publishing Ltd.
