  By P. Samarasekara*, D.P. Gunathilake, D.M.S.N. Kolugala, P.G.D.C.K. Karunarathna

  Abstract: A composite of CuO/Cu2O/Cu was synthesized by heating cupric acetate up to 600 °C for 2 hours in air. The properties of pure CuO films and CuO/Cu2O/Cu films were compared. Films were fabricated by the doctor blade method. Polyethylene glycol was used as a binder to prepare films. Mn was doped to composite to enhance the gas sensing properties. Compositions of Mn doped samples were confirmed using XRFS. According to …
