DOI: 10.1039/d2ra02199d
Abstract: This study assessed the effect of kaolinite edge surfaces on solid-state reactions. Specifically, Tb3+-doped metastable CaAl2Si2O8 showing green phosphorescence was prepared via a solid-state reaction between expanded kaolinite, a methoxy-modified kaolinite, having Tb3+ ions adsorbed… read more here.
