Materials
[0111]Y2O3, (99.9%), Yb2O3 (99.9%), Tm2O3(99.9%), CF3COONa (99.9%), CF3COOH, CaCO3, 1-octadecene (90%), oleic acid (90%), diethylene glycol (99%), toluene, citric acid monohydrate, 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC.HCl ), N-hydroxysulfosuccinimide sodium salt (sulfo-NHS), and branched polyethylenimine (PEI, Mw 25,000) were all purchased from Sigma-Aldrich and used without further purification. The trifluoroacetates of Y, Yb, and Tm were prepared as described. 5-carboxyfluorescein-bis-(5-carboxymethoxy-2-nitrobenzyl) ether, β-alanine-carboxamide, succinimidyl ester (CMNB-caged carboxyfluorescein, SE) were purchased from Invitrogen.
Preparation of Ln trifluoroacetates
[0112]Ln2O3 powder was mixed with a little of water to form a slurry in a single-neck flask, then trifluoroacetic acid with 150% stoichiometric ratio was added under stirring. When the exothermic process was finished, the single-neck flask was heated to reflux under water condenser....
