Notes:
We have obtained one-dimensional (1D) nanomaterials of tin oxide (SnO2) on siliconnitride (Si3N4)-coated Si substrates by carrying out the thermal evaporation of solid Sn powders andvarying the substrate temperature in an Ar/O2 ambient gas. We analyzed the samples with scanningelectron microscopy, X-ray diffraction, transmission electron microscopy and photoluminescence(PL). Reactions at a lower substrate temperature gave rise to thinner 1D structures. The obtained 1Dnanomaterials were single crystalline with a tetragonal rutile structure. We proposed a vapor-solidprocess as the growth mechanism for SnO2 nanorods. The PL spectrum exhibited visible lightemission
