吸附在纳米粘土上的有机染料与Langmuir-Blodgett（LB）膜之间的荧光共振能量转移
Fluorescence resonance energy transfer between organic dyes adsorbed onto nano-clay and Langmuir-Blodgett (LB) films
摘要：
本文研究了两种染料N，N' -双十八烷基硫菁高氯酸盐（NK）和十八烷基罗丹明B氯化物（RhB）在有或无合成粘土锂皂石的LB膜和LB膜中的应用。在纳米粘土片晶的存在和不存在下观察到的RhB的等温线的变化表明粘土片晶掺入到RhB-粘土混合膜上。AFM图像证实了粘土在混合膜中的掺入。在粘土分散体和LB膜中观察到FRET，有和没有粘土。能量传递效率最大的LB膜与粘土。
英文摘要：
In this communication we investigate two dyes N,N' -dioctadecyl thiacyanine perchlorate (NK) and octadecyl rhodamine B chloride (RhB) in Langmuir and Langmuir-Blodgett (LB) films with or with out a synthetic clay laponite. Observed changes in isotherms of RhB in absence and presence of nano-clay platelets indicate the incorporation of clay platelets onto RhB-clay hybrid films. AFM image confirms the incorporation of clay in hybrid films. FRET was observed in clay dispersion and LB films with and without clay. Efficiency of energy transfer was maximum in LB films with clay.
