 In this study, we investigated the properties of manganese thalocyanine, MNPC, films deposited by ultrasonic spray pyrolysis at different temperatures. We found that the films exhibit characteristic absorption bands in the visible region of the electromagnetic spectrum, which can be attributed to the presence of metallic thalocyanines. Furthermore, the Roman spectra of the films revealed the characteristic vibrational modes of MNPC. Additionally, the X-ray diffraction patterns of the films indicated the presence of a monoclinic phase. Finally, the SEM images of the films showed thicknesses of two micrometers for the deposited film and 1.2 micrometers and 0.3 micrometers for the annealed films at 100 degrees Celsius and 120 degrees Celsius, respectively.
