A facile wet chemical method is used for the preparation of the transition metal doped semiconducting materials. To prepare pure PVP encapsulated ZnO nano particles by taking 1g PVP which was dissolved in 50 ml of ethanol and the solution is stirred for 2 hours at room temperature. After the stirring process zinc nitrate of (0.5, 1.0, 1.5)g was added and to this solution add 0.1g of silver nitrate and stirr vigarously. The resultant product is kept aside for ten day, then dried under vacuuo and annealed.The synthesized nano material was preserved in an airtight container and it is subjected for various spectral investigation tools like X -Ray Diffraction analysis, High Resolution Scanning Electron microscope Analysis, Photoluminescence studies, Ultra Violet Absorption and Fourier Transform Infrared Spectroscopic studies. The XRD results reveal that the synthesized samples are in highly crystalline in state and also show that the sample does not contain any metal peak which shows that the synthesized samples are in highly pure phase. The HR SEM result shows that the materials are in Nano phase. The UV visible absorption spectroscopic study shows strong absorption peaks of ZnO around 295 nm and Ag doped ZnO around 280 nm which is caused by the band edge transition of the synthesized semiconductor. The FTIR studies are also shows characteristic peaks for PVP, ZnO, Ag doped ZnO nanocomposites. The ZnO nano material behaves as a potential antimicrobial agent but the silver doped ZnO shows a lesser activity while comparing with the standard drug (Streptomycin).
