The solution processed molecular semiconductors have attracted much attention due to their potential use for cheaper device manufacture. Among them copper phthalocyanine-3,4′,4″,4″′-tetrasulfonic acid tetrasodium salt (CuTsPc) is an emerging material having potential applications in optoelectronic and gas sensing devices. In the present work, CuTsPc thin films were deposited by drop-cast method on glass and quartz substrate. The absorption spectra of these films show two well defined absorption bands of phthalocyanine molecule, namely, the soret (B) and Q-band. The band gaps calculated from the absorption spectra is found to be lie in 1.55-4.04 eV. X-Ray diffractogram of the films indicate their polycrystalline nature. Atomic force microscope (AFM) investigations of the films show granular grain like morphology. The current-voltage (I-V) studies of the films show the ohmic conduction within the experimental region investigated..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
