The sensitivity increases almost linearly with the NO gas concentration up to 80 ppm, above which it is saturated to 0.94. For freshly prepared samples the SCLC was dominated by a single trapping level situated at Et≈0.58eV above the valence band edge. Based on spectroscopic measurements, we found all compounds show p ~ 0.1 Torr at 330°C and heat of vaporization, DeltaH ~ -23 kcal/more. John Mack and Nagao Kobayashi. Phase transitions in vanadyl phthalocyanine have been studied using differential scanning calorimetry, x-ray scattering and optical absorption spectroscopy. Recently, in collaboration with LASMEA, the same microelectronic device has been used to develop gas sensors on which the metal oxide layer is replaced by a phthalocyanine thin film. In this way, an overall view of the pattern of valence bands is obtained and the electronic structure determined in terms of the component partial densities of states. Recently phthalocyanines (Pc), a type of aromatic molecules containing 18 π-electrons on the organic ligand, have been employed in a wide range of applications.Copper-Pc (CuPc), commonly used for dying, has been found to have a great potential for organic solar cells, spintronics and quantum computation [1-3].The effort made to use CuPc as a magnetic switching has opened up a new field for . The disorder enhances the optical absorption at 6500 Å. These different trapping modes may be ascribed to adsorbed gaseous species in the former case and to a high concentration of structural defects resulting from a possible phase transformation in the latter. Accordingly, changes in the sensitivity to oxygen are followed as a function of substrate temperature. Villanueva A, Stockert JC, Cañete M, Acedo P.
