Abstract

Hybrid ZnO-SnO2 nanobelts were synthesized through a simple thermal evaporation technique without using any catalyst. Detailed microstructural investigation showed that the nanobelts possessed doped/alloyed wurtzite (ZnO) and rutile (SnO2) structures. The diameter and length of the nanobelts were in the ranges 100-200 and 20-40 mu m, respectively. Low-temperature photoluminescence properties of the hybrid ZnO-SnO2 nanostructured aggregate revealed a red shift of near-band-edge emission peaks of ZnO with increasing temperature. The method of synthesis offers a convenient and effective technique of producing hybrid ZnO-SnO2 nanobelts for gas sensing in the large quantity.
