Optical absorption and emission spectral studies of various phthalocyanine ( Pc ) molecules in dimethyl formamide (DMF) solvent are reported in this paper. Measurements have been done for free base, Eu , Fe , Mn , Sm , Cu , Zn , Nd and La Pc - s . The principal optical transitions viz B and Q are identified and some of the important spectral parameters such as molar extinction coefficient (ε), absorption cross section (σa), dipole strength (q) and oscillator strength (f) are evaluated for the prominent Q-band. The measured radiative parameters viz emission cross section (σe), fluorescence bandwidth (Δλ) and optical gain (G) show wide variation among different systems. The results obtained are compared with other solid matrices such as glass and polymer.
