Brucite structure doped with different amounts of Er(III) and their infrared emissions J. Aust. Ceram. Soc. (IF 1.307) Pub Date : 2020-08-31 Yufeng Chen, Yajiao Zhang, Jiwan Zhang, Chao Li, Li Wang
A series of brucite structure-doped samples with different amounts of Er(III) have been synthesized by hydrothermal method. Various characterizations have been employed to study the composition, structure, and photoluminescence. Results suggested that the Er3+-doped samples with Mg(II)/Er(III) molar ratio of 0.99/0.01~0.8/0.2 exhibited typical brucite structure, and the sample with Mg(II)/Er(III) molar

Green glazes were successfully prepared using ferrochromium slag waste as chromium and iron precursors by introducing Co2O3 as coloring agent. The performance of the glazes was investigated by XRD, EDS, FT-IR, and UV-vis. A chromatic mechanism was proposed to explain the variation of glaze colors with the increase of Co2O3 content. The results showed that the Co-doped glazes had Co-Fe-Cr mixed spinel-type
