Abstract
Monodisperse and spherical Eu-doped TiO2 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 TiO2 matrix with Eu3+ ions highly dispersed in it. The Eu-doped TiO2 nanodots exhibit intense luminescence due to effective energy transfer from amorphous TiO2 matrix to Eu3+ ions. The luminescence intensity is about 12.5 times of that of Eu-doped TiO2 film and the luminescence lifetime can be as long as 960 μs.
