Abstract: ZnO nanowires with excellent properties were synthesized by twostep method. Photoluminescence (PL) measurements showed that the ZnO nanowires
have stronger ultraviolet emission properties at 376 nm and there is a
5 nm blue shift after being immersed in thiourea (TU) solution compared with those of without immersion. The immersed ZnO nanowires show a turnon field of 2.3 V/μm at a current density of 0.1 μA/cm2 and emission current density up to 1 mA/cm2 at an applied field of 6.8 V/μm, which are 2.7 V/μm and 7.9 V/μm for those of without being immersed, respectively.
So this method may be an effective method to improve the characteristics
of ZnO nanowires.
