Spectroscopic investigation of two xanthane dyes and design of a FRET based pesticide sensor.

ABSTRACT: Layer-by-Layer (LbL) technique is the simplest and inexpensive method for preparartion of nano-dimensional thin films for tailoring material behavior having wide range of applications including sensors. Here, spectroscopic behavior of two laser dyes Acriflavine (Acf) and Rhodamine B (RhB) assembled onto LbL films have been investigated. It has been observed that both Acf and RhB form stable LbL films. Polyanion polyacrylic acid (PAA) was used to incorporate the Acf or RhB onto the LbL films. Adsorption of Acf and RhB onto PAA were completed within 45 min and 30 min respectively. During LbL film, material loss occurred in case of Acf. It has been demonstrated that such material loss can be minimized by incorporating clay laponite onto the LbL films. Temperature and pH dependant studies indi
