Abstract

Graphene is an atomic thin two-dimensional semimetal whereas ZnO is a direct wide band gap semiconductor with a strong light-emitting ability. In this paper, we report on photoluminescence (PL) of ZnO-nanowires (NWs)-core/Graphene-shell heterostructures, which shows a negative thermal quenching (NTQ) behavior both for the near band-edge and deep level emission. The abnormal PL behavior was understood through the charging and discharging processes between ZnO NWs and graphene. The NTQ properties are most possibly induced by the unique rapidly increasing density of states of graphene as a function of Fermi level, which promises a higher quantum tunneling probability between graphene and ZnO at a raised temperature.

ZnO NW-core/graphene-shell structure (a-c) Typical low-magnification TEM images show the ZnO NWs were covered with ultrathin graphene layers (d) a high-magnification image of the area as indicated by the arrow in (c) shows all of the ZnO NWs surfaces have been surrounded by graphene.

(a) Temperature-dependent intensity of A, B, C peaks as a function of temperature, the red solid line is the fitting curve using Eq. (2). (b)Temperature dependent defect emission in ZnO-NW core/graphene-shell structure.

Fig. 5
Fig. 5

Schematic band energy diagram between graphene and ZnO NWs, where Ec, Ev, Ef, ED represents conduction band, valence band, Fermi level and donor level, respectively. The holes assemble on the surface of ZnO NWs due to the up-conversion of valence band, which limits the exciton emission in the ZnO NWs. The recombinations giving rise to A, B emissions can be described as below: The photo-excited electron in ZnO is thermally emitted into graphene part and then the electron recombines with holes accumulated at ZnO surfaces with energy level of A and B. The C emission is a donor-acceptor pair (DAP) recombination.
