- Abstract
Eu-doped boehmite nanofiber materials with different Eu concentrations were synthesized without any surfactant, and followed by a series of characterizations. It was found that the boehmite nanofibers became coarser with the increase of Eu concentration, which resulted in a gradual decrease of their specific surface areas. Moreover, the thermal stability of the boehmite nanofibers was studied by thermogravimetry-differential scanning calorimetry. All materials showed the phase transition from γ-AlO to other forms. Yet the transition temperature was increased with the increase of Eu concentration. The Eu-doped boehmite nanofibers with the maximum Eu concentrations showed the best thermal stability. Photoluminescence spectra showed that the 2 mol% of doping concentration of Eu ions in Eu:AlO nanofiber was optimum.
