Enhanced Luminescence of Eu-Doped TiO(2)Nanodots

Monodisperse and spherical Eu-doped TiO(2)nanodots were prepared on substrate by phase-separation-induced self-assembly. The average diameters of the nanodots can be 50 and 70 nm by changing the preparation condition. The calcined nanodots consist of an amorphous TiO(2)matrix with Eu(3+)ions highly...

description Monodisperse and spherical Eu-doped TiO(2)nanodots were prepared on substrate by phase-separation-induced self-assembly. The average diameters of the nanodots can be 50 and 70 nm by changing the preparation condition. The calcined nanodots consist of an amorphous TiO(2)matrix with Eu(3+)ions highly dispersed in it. The Eu-doped TiO(2)nanodots exhibit intense luminescence due to effective energy transfer from amorphous TiO(2)matrix to Eu(3+)ions. The luminescence intensity is about 12.5 times of that of Eu-doped TiO(2)film and the luminescence lifetime can be as long as 960 μs.
