Abstract

This study assessed the effect of kaolinite edge surfaces on solid-state reactions. Specifically, Tb-doped metastable CaAlSiO showing green phosphorescence was prepared a solid-state reaction between expanded kaolinite, a methoxy-modified kaolinite, having Tb ions adsorbed on its edge surfaces and CaCO. This material cannot be obtained by the conventional grinding of kaolinite, CaCO and TbO, indicating that the use of kaolinite edge surfaces is advantageous as a means of achieving certain solid-state reactions.

摘要

本研究评估了高岭石边缘表面对固态反应的影响。具体而言,通过在膨胀高岭石(一种甲氧基改性高岭石,其边缘表面吸附有Tb离子)与CaCO之间进行固态反应,制备出了呈现绿色磷光的掺Tb亚稳CaAlSiO。这种材料无法通过对高岭石、CaCO和TbO进行常规研磨获得,这表明利用高岭石边缘表面作为实现某些固态反应的一种手段具有优势。
