Spectroscopic properties Pr3+ doped transparent oxyfluoride glass ceramic
In this paper, we reported the spectroscopic properties of praseodymium ions (Pr3+) doped transparent oxyfluoride glass ceramic excited with different laser lines, such as 532, 514.5 and 476.5 nm. and the spectroscopic features of Pr3+ ions in LaF3 nanocrystals (NCs) and in oxide glass were presente...

| description | In this paper, we reported the spectroscopic properties of praseodymium ions (Pr3+) doped transparent oxyfluoride glass ceramic excited with different laser lines, such as 532, 514.5 and 476.5 nm. and the spectroscopic features of Pr3+ ions in LaF3 nanocrystals (NCs) and in oxide glass were presented. It was found that the population on 3P0 state of Pr3+ ion in NCs and in glass can be achieved by multi-phonon assistance process when excited by 514.5 nm laser lines. As a comparison, 476.5 nm laser line which is mainly resonant with the 3H4 to 3P0 transition of Pr3+ ions in NCs is used as the excitation source, transitions from 3P0 state to many lower states, such as 3H5, 3H6, 3F2 manifolds were observed and it showed significant difference from those excited by 532 nm and 514.5 nm laser lines in which only transition from 3P0 to 3H5 exists. We attribute those different spectroscopic features as selectively excitation of Pr3+ ions in different environments where exist strong/weak electron-phonon coupling in the 3P0,1 states of Pr3+ ion in NCs and in glass. Crystallization behavior and vibrational properties of transparent glass ceramic were also stu-died by Raman spectroscopy excited by 532 nm and 514.5 nm laser lines. |
