Abstract:
Highly uniform and monodisperse Y2O3：Eu3+ nanorods and nanotubes were successfully prepared in large quantities using a facile hydrothermal approach assisted by a capping reagent, PEG-2000. CheaperNaOH，Y(NO3)3·6H2O andEu(NO3)36H2O were used as the raw materials. The formation mechanism of Y2O3：Eu3+ nanorods and nanotubes were discussed. The results showed that the morphologies of Y2O3：Eu3+ were depended on the different reaction temperatures, reaction time, the addition of NaOH and PEG2000, and the prepared material had characteristic red emission of Eu3+, while identifying 5% Eu3+doped Y2O3 had the best property of luminescence.
