SiO2-SnO2:Er3+ transparent glass-ceramics
Abstract
<p>This work focuses on the fabrication processes and photonic assessment of SiO<sub>2</sub>-SnO<sub>2</sub>:Er<sup>3+</sup> monoliths. To obtain the crack-free and densified system, the sol-gel derived synthesis protocols and heat-treatment processes were optimized. The absorption measurements were employed to assess the effect of the heat-treatment on the samples and specially to estimate the -OH content. The XRD patterns were used to investigate the crystallization as well as the structure of the monoliths. The emission spectra, performed at different excitation wavelengths, evidence the presence of Er<sup>3+</sup> in the SnO<sub>2</sub> nanocrystals and the energy transfer from SnO<sub>2</sub> to the rare earth ions. In addition, the efficient role of SnO<sub>2</sub> nanocrystals as Er<sup>3+</sup> sensitizers are also experimentally confirmed in this system.</p>
