采用水热合成法成功制备了层状化合物Cl-LGdH：Eu,并且通过离子交换成功将对苯二甲酸(PTA,p-phthalic acid)、1,3,5-苯三甲酸(BTA,1,3,5-benzenetricarboxylic acid)和均苯四甲酸(PA,Pyromellitic acid)分别嵌入到Cl-LGdH：Eu中,形成有机-无机复合纳米材料PTA-LGdH：Eu、BTA-LGdH：Eu和PA-LGdH：Eu.XRD结果表明,含苯环的有机敏化剂的嵌入明显增大了层状化合物的层间距.荧光光谱结果表明,Cl-LGdH：Eu发光较低是由于Cl-不能有效的吸收能量,而由于有机功能小分子的共轭效应,有效的将光能传给基板中的Eu3+,使其跃迁到激发态,从而使得发光增强.
