Organic Phthalocyanine (Pc) material is studied when Zn cation is inserted in such molecule. Effect of zinc cation on nonlinear optical properties is evidenced. Experimental Raman spectrum and theoretical spectrum of ZnPc cluster using DFT method are investigated. Absorbance profile of Phtalocyanine (Pc) and Zincphthalocynanine (ZnPc) using TDDFT approximation technique and experimental are compared. The density of states DOS are plotted and LUMO- HOMO energies are found to be -2.28 and − 7.41 eV for Pc and − 2.28 and − 6.08 eV for ZnPc. High transparency of ZnPc film is observed within visible band and optical band gap of 3.83 eV is determined. Evaluated at 1.4 eV Urbach energy of ZnPc is then determined. A (213)-oriented monoclinic crystalline structure of ZnPc thin film is observed by X-ray pattern. A selective wavelength of 360 nm is recorded and filter optical properties are confirmed. High rectifying behavior of ZnPc/Si/Al is demonstrated and SCLC conduction mechanism is dominant inside the organic device.
