Effect of dopant precursors on the optical properties of rare‐earths doped oxyfluoride glass‐ceramics

[EN] TThe crystallization of fluoride nanocrystals (NCs) in chemically and mechanically stable aluminosilicate glasses has shown interesting optical properties even for small crystal fractions (10‐15 wt%). When rare‐earth (RE) ions are used as dopants, crys-tal‐like features can be reproduced and an...

When rare‐earth (RE) ions are used as dopants, crys-tal‐like features can be reproduced and an increase in the emission and/or energy transfer processes, with respect to the starting glasses, is observed. A crucial point for these materials is the study of the local surrounding of RE ions and their incorpora-tion in the NCs. In fact, the effective concentration in the NCs can be much higher than the nominal concentration, up to one order of magnitude or even higher. The knowledge of RE ions incorporation in the NCs permits choosing proper doping lev-els to optimize both linear and nonlinear optical properties. In this work, transparent oxyfluoride glass‐ceramics with LaF3 NCs, doped with Nd3+ and Er3+ using oxide and fluoride precursors, were prepared using the melt‐quenching method and con-trolled crystallization. The local surrounding of the RE ions was studied using X‐ray absorption spectroscopy, electron paramagnetic resonance and photoluminiscence.
