Facile Solvothermal Method to Synthesis Eu Doped TiO₂ Hollow Microspheres with Enhanced Photoluminescence

Abstract:

Eu doped TiO₂ powders have been prepared by the solvothermal process followed by calcination treatment. The furfural and dodecylamine assisted solvothermal method is a very simple way of fabricating porous TiO₂ hollow spheres due to in situ hydrolysis and a self-assembled effect. By adding europium nitrate into the precurso_{Subscript text}r solution, Eu-doped TiO₂ hollow spheres with an intense photoluminescence were easily obtained. The stronger photoluminescence of Eu-doped TiO₂ hollow sample can be attributed to the unique microstructures, such as uniform size distribution and the broken hollow structure, compared to solid Eu-TiO₂ sample.
