摘要：
In this work, we present novel trivalent lanthanide ions(Ln;)-based luminescent hybrid materials, in which the organic ligands are covalently grafted on the hectorite templates and the Ln;ions can be well immobilized by the ligands through coordination bond. The hybrid materials exhibit tunable emission colors by varying the molar ratio of Eu;to Tb;, and the one with Eu;:Tb;=1:1 exhibits excellent coordinate of（0.327, 0.328） located in the "white region" of the CIE 1931 chromaticity diagram（under300 nm UV illumination）. These properties make the hybrid composites suitable for fabricating optoelectronic devices such as full-color displays and white LED.
