Tin oxide (SnO2) nanostructured thin film with different immersion times was prepared on zinc oxide (ZnO) seeded catalyst using immersion method. The immersion times were varied at 3.0, 3.5 and 4.0 hours. Field emission scanning electron microscopy (FESEM) and two point probes current-voltage (I-V) measurements were used to study the surface morphology and electrical properties of SnO2 nanostructured thin films. The diameter size of SnO2 nanostructures which immersed at 3.0, 3.5 and 4.0 h were in range 10-20 nm, 20-30 nm and 30-50 nm, respectively. The results shows the highest electrical properties was at 3.0 h of immersion time.
