- The undoped, and Er-doped yttrium aluminozirconate (AYZ) glasses were prepared by flame synthesis in the form of transparent glass microbeads. The $ZrO_{2}$ content was in the range between 5 and 20 mol. %. The prepared glass microbeads were characterised by optical microscopy, SEM, XRD, DSC, $\text{}^{27}Al$ MAS NMR, UV-VIS-NIR and fluorescence spectroscopy. The thermal stability of AYZ glasses, expressed in terms of the difference between the glass transition temperature, $T_{g}$, and the onset of crystallization, $T_{x}$, was not affected by the increasing $ZrO_{2}$ content. The $\text{}^{27}Al$ MAS NMR spectra of studied glass samples reveal that Al atoms are predominantly 4-coordinated in glasses. The AYZ5 and AYZ10 basic glasses were doped with $Er^{3+}$ at the level of 1-5 mol. % of $Er_{2}O_{3}$. The UV-VIS-NIR/fluorescence spectra show characteristic absorptions/emissions, due to the optically active $Er^{3+}$ ions in the host glasses. The absorption/emission properties of guest ions are not significantly affected by the glass host.
