| description | <p>Abstract</p> <p>Monodisperse and spherical Eu-doped TiO<sub>2</sub>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<sub>2</sub>matrix with Eu<sup>3+</sup>ions highly dispersed in it. The Eu-doped TiO<sub>2</sub>nanodots exhibit intense luminescence due to effective energy transfer from amorphous TiO<sub>2</sub>matrix to Eu<sup>3+</sup>ions. The luminescence intensity is about 12.5 times of that of Eu-doped TiO<sub>2</sub>film and the luminescence lifetime can be as long as 960 μs.</p> |
