Effect of kaolinite edge surfaces on formation of Tb(3+)-doped phosphor by solid-state reaction

This study assessed the effect of kaolinite edge surfaces on solid-state reactions. Specifically, Tb(3+)-doped metastable CaAl(2)Si(2)O(8) showing green phosphorescence was prepared via a solid-state reaction between expanded kaolinite, a methoxy-modified kaolinite, having Tb(3+) ions adsorbed on it...

Sumario:This study assessed the effect of kaolinite edge surfaces on solid-state reactions. Specifically, Tb(3+)-doped metastable CaAl(2)Si(2)O(8) showing green phosphorescence was prepared via a solid-state reaction between expanded kaolinite, a methoxy-modified kaolinite, having Tb(3+) ions adsorbed on its edge surfaces and CaCO(3). This material cannot be obtained by the conventional grinding of kaolinite, CaCO(3) and Tb(2)O(3), indicating that the use of kaolinite edge surfaces is advantageous as a means of achieving certain solid-state reactions.
