Abstract: The application of Nanostructured materials is enormous as their physical and chemical properties depend upon size. Here an attempt is made first time to synthesis (Srx Cu1-xO) nanoparticles by sol–gel method. Sr(No3)2and Cu(No3)2.3H2O were taken as starting material. Ethanol, distilled water and PVA are mixed with these powders of nitrates and solution was stirred by magnetic stirrer at a temperature of 80 0C till a gel was formed. It was then dried at low temperature and finally calcinated at 400 0C for four hours. XRD of the sample shows its crystalline nature and particle size was determined to be 34nm by Debye Schherrer formula. The FTIR study shows two broad peak at 1455 cm-1 and 532 cm-1 . The UV-VIS analysis shows a absorption peak at 202nm .The TEM images clearly shows the individual nanoparticles having diameter less than 20 nm. In one image a nano rod is also visible whose further study is also required.
