Characterization of Waste Material Derived Willemite-Based Glass-Ceramics Doped with Erbium

Abstract EN

We reported, for the first time, to the best of our knowledge, the production of erbium doped willemite-based glass-ceramic using waste material.

In this work, a willemite-based glass-ceramic was prepared from waste material to obtain excellent crystallinity and then doped with trivalent erbium (Er3+) to yield ([(ZnO)0.5(SLS)0.5]1−x[Er2O3] x) final composition where x = 3 wt%.

The samples were sintered at various temperatures (500–1100°C) to study the effects of sintering temperatures on microstructure and physical properties of the samples.

X-ray diffraction (XRD) and Fourier transform infrared (FTIR) were used to determine structural changes and functional groups in the samples, respectively.

Field-emission scanning electron microscopy (FE-SEM) equipped with energy dispersive X-ray was used to observe surface morphology and to detect presence of elements in the samples.

Findings showed that average grain size of the Er3+ doped glass-ceramic sample increased as a function of the sintering temperature and the optimum temperature was 900°C.
