Enhanced emission in composite multilayers of amorphous TiO2-gel and Eu3+ ions
Ultrathin films of (TiO2)/Eu3+)(n) and (TiO2/PAA/Eu3+)(n) composites were prepared by the surface sol-gel process and the subsequent chemisorption/coordination of Eu3+ ions. Amorphous TiO2-gel layers were found to act as sensitizer for efficient emission of Eu3+.
