Original Abstract
In this work novel 5,10,15,20 meso-tetraphenyl porphyrin (H2TPP) films have been deposited by means of a new physical technique named glow discharge induced sublimation (GDS). A preliminary characterization has been performed by means of scanning electron microscopy (SEM) and Fourier transform infra-red (FT-IR) analyses. SEM images and infra-red analyses highlight the great surface roughness and the high purity of GDS films, respectively. For comparison, H2TPP films have been also deposited by means of spin coating (SPIN) technique. Optical sensing measurements, performed in differently concentrated ethyl alcohol (EtOH) atmospheres, highlight that GDS samples yield higher response intensities than SPIN films, very short response times and complete recovery.
