The sensor is based on a novel vapochromic material, which is able to change its optical properties in presence of organic vapors in a reversely way. A nano Fabry Perot is constructed onto a cleaved ended optical fiber pigtail by Electrostatic Self Assembly method (ESA), doping this structure with the vapochromic material. Employing a reflection scheme, a change in the intensity modulated reflected signal at 850 nm have been registered. The response of the sensor has been evaluated for five different VOCs, and a deeper study has been made for vapors of three different alcohols.application/pdfeng© 2006 by MDPI.
