Spectral Studies Of Naphthalocyanine (Nc) And Rare Earth Phthalocyanine (Repc) Molecules In An Inorganic Glassy Borate Matrix

Optical absorption and emission spectral studies of free and metal naphthalocyanine doped borate glass matrix are reported for the first time. Absorption spectra recorded in the UV-VIS-NIR region show the characteristic absorption bands, namely, the B-band and Q-band of the naphthalocyanine (Nc) molecule. Some of the important spectral parameters, namely, the optical absorption coefficient, molar extinction coefficient and absorption cross section of the principal absorption transitions are determined.
