Procedure

Dissolve anhydrous salts such as Yttrium chloride (YCl3) in pure ethanol. Add a known quantity of potassium to ethanol and make potassium ethoxide, KOC2H5. Mix this with YCl3 in ethanol and stir. Under refluxing, a clear solution of yttrium ethoxide and a precipitate of potassium chloride is obtained. The dopant Eu can similarly be added to the Yttrium chloride in ethanol at first and this reaction would form Yttrium europium ethoxides. The ethoxides can then be hydrolyzed by adding a solution of ammonia at room temperature. These products are separated and can then be deposited by various means outlined earlier.
