Abstract : The Rare Earth prasedymayam is doped at different concentrations like 1%,2%,3% in Mn2+ ion co doped in ZnO host Nano material. The chemicals are Zinc nitrate hexa hydrate (Zn(NO3)2.6H2O), Manganese acetate tetra hydrate Mn(CH3COO)2.4H2O, Cerium nitrate hexa hydrate, (Pr(NO3)3.6H2O), Urea CH4N2O, NH3 and polyethylene glycol (PEG-400) of AR grade (Sigma Aldrich 99.99%) used without further purification The samples were subjected to various characterization studies . Its photoluminescence studies shows its a good absorbent and Energy gap reduces as concentration increases. The electrochemical studies were done by using KOH and plots were drawn for Vi characteristics .Then they found very Low RHE potential indicates speed charging and discharging of fuel cell. It’s a very soft material. It cannot be taken as pellets. It shows gas sensing of Nontoxic gases like NH4 (Ammonia) at high PPM values.
