This article reports the preparation of ZnO-SnO2 nanocomposites from ZnO and SnO2 nanoparticles produced by homogenous precipitation route. Zinc acetate dihydrate (Zn(CH3COO)2 x 2H2O) and tin(II) chloride dehydrates (SnCl2. 2H2O) have been used as precursors. Distilled water was used as a solvent, monoethanolamine (MEA) is used as sol stabilizer. Precursors individually dissolved and stirred at 60 degrees C for 1 h. Certain amount of MEA were added to solution and stirred for 2 h. Then solution was cooled to room temperature and gets precipitated. The collected nanosized precipitates were mixed together and deposited on glass substrates by drain coating and post-heated at different temperatures. X-ray diffractometer was used to determine preferred crystal orientation and particle size of the thin films. Morphologies of nanopowders were examined by scanning electron microscope (SEM).
