INVESTIGATION OF OPTICAL AND STRUCTURAL PROPERTIES OF TIN OXIDE-PORPHYRIN STRUCTURES FOR OPTICAL SENSORS APPLICATION
Tin oxide-porhyrin structures deposited on glass substrates have been investigated for 2-Mercaptoethanol detection. Tin oxidelayer was deposited by electro-spray pirolysis. Porphyrin layers were grown by dipping the substrates into porphyrin solution in waterand toluene. Structural properties were characterized by XRD and AFM methods. Optical transmittance in range of 200- 1100 nm ofthe structures was performed before and after adsorption of 2-Mercaptoethanol on their surfaces. Optical response of the structuresto 2-Mercaptoethanol at room temperature is reported. The influence of 2-Mercaptoethanol adsorption to optical transmittance wasdiscussed.
