Claim 0:
1. A method for making zirconium doped terbium nano oxides, the method comprising:
dissolving terbium nitrate (Tb(NO3)3.6H2O) and zirconium nitrate hydrate (Zr(NO3)3.xH2O) in water to obtain a solution;
adjusting pH of the solution to about 7.5 by dropwise addition of a solution of NaHCO3;
stirring to obtain a homogenous solution containing zirconium (Zr(CO3)2.xH2O) and terbium (Tb2(CO3)3.xH2O) carbonate precipitates;
centrifuging and drying the homogenous solution to obtain Zr(CO3)2 and Tb2(CO3)3 metal carbonates;
calcinating the Zr(CO3)2 and Tb2(CO3)3 metal carbonates at a temperature of about 825° C. to about 875° C.; and
obtaining the zirconium doped terbium nano oxides (ZrTb2O3).
