Synthesis and characterization of N- and P- doped tin oxide nanowires

Bulk-scale synthetic methods for preparing doped tin oxide (SnO
₂
) nanowires (NWs) are presented. n-and p-doping is achieved through insertion of Antimony and Lithium in tin oxide lattice, respectively. We also present a comparison of the structural and optical properties of SnO
₂
nanoparticles (NPs), and SnO
₂
NWs. Both n-type and p- type NWs display a characteristic red shift in their photoluminescence (PL) spectra. Surface plasmons observed in these systems imply high carrier concentrations. These corrosion resistant materials are useful in fabricating ultra-sensitive gas detectors and transparent electronics.
