Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Luminescence and Time-Resolved Emission Spectra of Nd<sup>3+</sup>and Er<sup>3+</sup>: Silver Zinc Borate Glasses

  • Coelho, João
Abstract

<jats:p>The paper reports the visible-NIR luminescence and time-resolved emission spectral profiles of Nd<jats:sup>3+</jats:sup>, and Er<jats:sup>3+</jats:sup> doped silver zinc borate glasses. Steady state luminescence (SSL) and time-resolved emission spectroscopy (TRES) were used to evaluate how the randomness of the network can influence the emission from rare earth ions in the visible region. As expected the composition of the glasses strongly influences the emission bands of the dopant ions. The lack of homogeneity in the glass network results in distorted and broad luminescence spectra. Moreover, time-resolved techniques allowed the visualization of the time dependence of the spectra. The luminescence was also characterized using steady state techniques and the strongest NIR emission peaks were <jats:sup>4</jats:sup>F<jats:sub>3/2</jats:sub> à <jats:sup>4</jats:sup>I<jats:sub>l1/2 </jats:sub>for Nd <jats:sup>3+</jats:sup> and <jats:sup>4</jats:sup>I<jats:sub>13/2</jats:sub> à <jats:sup>4</jats:sup>I<jats:sub>l5/2 </jats:sub>for Er<jats:sup> 3+</jats:sup> ions respectively.<jats:italic>Key words:</jats:italic> Time-resolved emission spectra; decay associated spectra; Nd<jats:sup>3+</jats:sup> and Er<jats:sup>3+</jats:sup>; Silver zinc borate glasses</jats:p>
