THERMAL AND RAMAN SPECTROSCOPIC ANALYSIS OF COBALT-CONTAINING PHTHALOCYANINE PIGMENT
This study presents detailed thermal analysis and Raman spectroscopic data of the synthesized cobalt phthalocyanine pigment. Thermal analysis was used to determine the thermal stability and decomposition temperatures of the pigment, while Raman spectroscopy provided insights into its molecular structure and chemical bonding. In addition, the pigment’s optical properties, including its absorption and photoluminescence spectra in various solvents, were investigated to assess its light absorption capacity and emission intensity. The results demonstrate that the pigment is not only promising for use in industrial coatings but also as a high-performance material for optical applications and dye-sensitized solar cells.
