中文摘要：

通过有效控制合成液配比,合成出了形貌规则、结晶度高且具有不同长径比的LTL型分子筛晶粒。采用＂瓶中造船法＂,在不同长径比的LTL型分子筛晶粒孔道中组装稀土有机配合物,制得LTL分子筛/Eu-TTA主-客体荧光材料。荧光光谱表征结果表明,在激发波长为350 nm时,长径比为0.2的LTL分子筛/Eu-TTA晶粒在617 nm处的^5D0→^7F2发光强度最大,而长径比为3的晶粒发光强度最小。最后,将长径比为0.2的LTL分子筛/Eu-TTA晶粒在PEI修饰的玻璃表面快速擦涂10 s后,就制得厘米尺寸的一维取向LTL型分子筛荧光阵列。SEM表征结果证实,该分子筛荧光阵列中几乎所有的LTL分子筛晶粒都沿着与底基表面垂直的c轴方向一维高密度、单层有序排列。在激发波长为365 nm时,该一维取向LTL分子筛荧光阵列发出鲜艳的红色荧光。

英文摘要：

LTL type zeolite crystals with regular morphology,high crystallinity and different aspect ratio were successfully synthesized by adjusting the composition of the synthesis gel. Then,the organolanthanide complexes were loaded inside of the zeolite LTL channels,denoted as zeolite LTL /Eu-TTA,by using the ‘ship-in-bottle＇ method. The luminescence spectra analysis results show that the zeolite LTL / Eu-TTA crystal with 0. 2 aspect ratio has the strongest emission of ^5D0→^7F2located at 617 nm,whereas the crystals with aspect ratio of 3 has the weakest one under the excitation of350 nm. Finally,The fluorescent array extending to the centimeter scale was fabricated in an oriented way by rapid wiping the zeolite LTL / Eu-TTA crystals with 0. 2 aspect ratio in 10 s on the surface of PEI coated glass substrate. SEM results prove that nearly all zeolite LTL crystals compact closely with their c-axial perpendicularly to the glass surface in a monolayer manner. This one-dimensional orientated fluorescent array can issue bright red light under the excitation of 365 nm.
