一维取向LTL型分子筛荧光阵列的快速组装
Rapid Assembly of One-dimensional Orientation LTL Zeolite Fluorescent Array
摘要
Abstract
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 or-ganolanthanide 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 5 D0→7 F2 located at 617 nm, whereas the crystals with aspect ratio of 3 has the weakest one under the excitation of 350 nm. Finally, The fluorescent array extending to the centimeter scale was fabricated in an orien-ted 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.关键词
