Abstract

Nanostructured transparent glass-ceramics with composition of 95SiO₂-5LaF₃ doped with 0.1 mol% of Tm³⁺ or co-doped with 0.1 mol% of Tm³⁺ and 0.3 mol% of Yb³⁺ were synthesized by thermal treatment of precursor sol-gel denved glasses. A comparative luminescence analysis in terms of different temperatures of thermal treatments has been carried out. Segregation of LaF₃ nanocrystals in matrix was confirmed by X-ray diffraction. Blue and red efficient up-conversion emissions were observed under 980 nm excitation at room temperature. These resuits indicate partition of a significant fraction of co-dopants into the precipitated LaF₃ nanocrystals. The mechanisms involved in the up-conversion emissions have been analyzed and can be ascribed to processes with two, three and four photons.

<EA>Nanostructured transparent glass-ceramics with composition of 95SiO<sub>2</sub>

 doped with 0.1 mol% of Tm<sup>3+</sup>
 or co-doped with 0.1 mol% of Tm<sup>3+</sup>
 and 0.3 mol% of Yb<sup>3+</sup>
 were synthesized by thermal treatment of precursor sol-gel denved glasses. A comparative luminescence analysis in terms of different temperatures of thermal treatments has been carried out. Segregation of LaF<sub>3</sub>
 nanocrystals in matrix was confirmed by X-ray diffraction. Blue and red efficient up-conversion emissions were observed under 980 nm excitation at room temperature. These resuits indicate partition of a significant fraction of co-dopants into the precipitated LaF<sub>3</sub>
 nanocrystals. The mechanisms involved in the up-conversion emissions have been analyzed and can be ascribed to processes with two, three and four photons.</EA>
