Blending Ratio Effect of ZnPc/ZnO Hybrid Nanocomposite on Surface Morphology and Structural Properties

Abstract

Recently, organic/inorganic hybrid nanocomposites being the future in electronic applications. In this paper, we have investigated hybrid nanocomposite zinc phthalocyanine (ZnPc)/zinc oxide nanoparticles (ZnO). ZnPc/ZnO hybrid nanocomposites were prepared with different ratios (wt/wt) (1/0), (0/1), (0.75/0.25), (0.5/0.5), (0.25/0.75), and, deposited on glass substrates by spin coating technique. X-Ray diffraction investigate the structural of ZnPc/ZnO thin films and studied the morphological properties using field emission scan electron microscopy, the surface of ZnPc/ZnO hybrid nanocomposites shows the presence of nanorod-like structures represented the organic material (ZnPc) and spherical nanoparticles for (ZnO), that is depending on the ratio of the blend. In ratio (0.5/0.5) we get the preferred homogeneous surface between like-nanorod and spherical shapes were show various properties from pure compounds which used to prepare the blend. The distribution of ZnO nanoparticles on ZnPc particles nanorods led to the disappearance feature of ZnO morphological characterize and ZnPc decorated was dominated on the hybrid nanocomposite structure.

Macrocyclic Compounds: Metal Oxide Particles Nanocomposite Thin Films Deposited by MAPLE

“…Lately, a hot research topic has consisted of designing and developing organic–inorganic nanocomposites as thin films with tailored properties, owing to their wide range of applications in fields such as optoelectronics, sensing, medicine, surfaces with controlled wettability, etc. [ 1 , 4 , 6 , 7 , 8 ]. Among the organics, highly conjugated heteroaromatic macrocyclic compounds such as porphyrins and their synthetic analogues (phthalocyanines) have shown remarkable properties, such as intense absorption in the visible domain, structural flexibility, and compatibility with plastic substrates [ 9 , 10 , 11 ].…”

“…These organic materials are of interest in different application areas: optoelectronics (non-linear optical materials [ 12 ], photovoltaic cells [ 13 ], and organic light-emitting diodes [ 14 ]) and medicine (photodynamic therapy [ 15 , 16 ]). Moreover, metal phthalocyanines are cheap, nontoxic, and stable (chemically and thermally) semiconductors that can be used in various devices [ 3 , 7 , 11 , 17 ]. The inorganic nanostructures to be embedded into an organic matrix in order to obtain nanocomposite thin films must feature an adequate morphology and size [ 18 ].…”

“…Organic–inorganic systems based on phthalocyanine (or porphyrin derivatives) and inorganic semiconductors were investigated for their suitability in photovoltaic cells [ 25 , 26 , 27 ], chemical gas sensors [ 7 , 28 , 29 ], photocatalysis [ 3 ], the biomedical field [ 30 ], etc. Although different wet preparation methods (sol–gel [ 31 ], Langmuir–Blodgett [ 32 ], cathodic electrodeposition [ 25 ], etc.)…”

“…Although different wet preparation methods (sol–gel [ 31 ], Langmuir–Blodgett [ 32 ], cathodic electrodeposition [ 25 ], etc.) were used for preparing such hybrid films with suitable properties for a target application, spin-coating remains the most accessible technique for the deposition of nanocomposite films [ 7 , 33 , 34 ]. However, spin-coating requires a highly concentrated solution (of which even 95% is lost during the deposition process) and substrates characterized by a certain wettability and size make this method inaccessible in some conditions [ 7 , 35 , 36 ].…”

Moreover, the properties (such as the boiling point, vapor pressure, and evaporation rate) of the solvent implied in the fabrication of the mixed layers have a great impact on their morphology and roughness [ 37 ].…”
