Concentration Dependent Optical Properties Of Porphyrins In Nafion Matrix

• Concentration dependent optical properties of the various types of porphyrin compounds were studied using optical absorbance and Z-scan measurements. Enhanced absorbancewidth of the Soret and Q-bands have been observed by blending three different porphyrin molecules in Nafion column matrix membrane. This is an important development towards achieving efficient photon-harvesting medium for possible application in photonic devices. Moreover, new evidences have been found on the concentration dependance of the nonlinear absorption coefficient (β) of the VTPP in Nafion.
