Procedure

Sol-gel libraries were deposited on silicon wafer substrates. Stock solutions of yttrium isopropoxide, aluminum isopropoxide, gadolinium isopropoxide and gallium isopropoxide were prepared in 2-methoxyethanol (0.25 M) refluxing under Argon for 8 hours. To each of the four stock solutions of yttrium, gadolinium, aluminum and gallium in methoxyethanol (0.25 M), 1 equivalent of 2,4-pentandione was added with stirring, followed by the addition of anhydrous ethylene glycol (15% v/v). The yttrium and gadolinium solutions contained Ce(NO)3.6H2O at 1.0 mol % as the dopant source.
