We report a facile synthesis of Poly vinyl pyrrolidene (PVP) assisted Ceria (CeO2) nano particles by
modified Co-precipitation method. The particles were nucleated by mixing aqueous solution of Ce (NO3)3.6H2O, strong
base sodium hydroxide (NaOH) and weak base ammonia (NH3) as precipitation agent at room temperature separately.
The organic molecule such as Poly vinyl pyrolodivine (PVP) was chosen as surfactant and injected into the reaction
medium at the beginning of the synthesis. The thermal history of the precursor was examined using Thermo gravimetric
analysis. The effect of precipitation agent is found in the synthesis of CeO2 nano particles in the way of structure,
morphology, photo luminescence studies. Consequently, Sodium hydroxide is the most effective precipitation agent on
synthesis of CeO2 and mechanism of formation CeO2 nano particles were discussed.
