Preparation and Study on Spectrum Characteristics of Sr0.99 Ce0.01 HfO3 Nanopowders

摘要：

The Sr0.99Ce0.01 HfO3 nanopowders were synthesized by the co-precipitation method. The calcination temperature and time of the powders were 1200 ℃ and 2 h, respectively. The powder size of Sr0.99Ce0.01HfO3 nanopowders was 15 ～30 nm. There were two excitation bands in the excitation spectra of the Sr0.99Ce0.01HfO3 nanopowders, which peaking at 216 and 309 nm, respectively. There were two emission bands in the emission spectra excited by the 220 nm light, which peaking at 398 and 467 nm. And they were corresponding to the 5d→2F5/2 and the 5d→2F7/2 transitions of Ce3+ ions. But there was only one emission band in the emission spectrum excited by the 309 nm light which peaking at 392 nm.
