Luminescent SiO(2)-coated Gd(2)O(3):Eu(3+) nanorods/poly(styrene) nanocomposites by in situ polymerization
Europium doped gadolinium oxide nanorods have been coated with silica via a sol–gel approach. The silica coating increases the Eu3+ absolute emission quantum yields from 0.51 to 0.86 (255 nm excitation) and decay times from 1.43 to 1.80 ms (394.4 nm excitation). Subsequently the silica coating was m...
