Description
Summary:Indium–tin–oxide (ITO) nanorods were fabricated in 10 min from commercially available ITO substrate using wet chemical etching method. The optical properties of the ITO nanorods were investigated using transmission spectroscopy and dark-field optical microscopy. The transmittance and light-scattering characteristics of the ITO nanorods were better than those of ITO film. The ITO nanorod layer was further used as a transparent anode in polymer light-emitting diodes (PLEDs). The brightness and current efficiency of the PLED with the ITO nanorod layer were enhanced. This performance enhancement can be attributed to the excellent optical and electrical properties of the ITO nanorod layer.
