Abstract:
Linear and nonlinear optical properties of five kinds of zinc phthalocyanines (ZnPcs) were investigated using UV-Vis absorption spectra, fluorescence spectra and Z-scan measurements. The influence of concentrations on the optical properties of zinc phthalocyanine (ZnPc) was also studied. Linear optical results show that the five investigated ZnPcs are fluorescent, while nonlinear optical results show that they are effective reverse saturable absorption materials. The concentrations have drastically influenced the linear and nonlinear optical properties of ZnPc.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
