Abstract
The series of sol-gel synthesis was prepared using different organic and inorganic acids and bases, and with different polarity of solvents, and with various concentration of the luminophore to immobilize zinc phthalocyanine to the matrix. Immobilization was achieved by coordination of zinc phthalocyanine in the axial position with isonicotinamide substituted by alkoxysilane. By using siloxane precursors, matrices of variable hydrophilicity were obtained by the sol-gel method in order to select the optimal environment for phthalocyanine immobilization. The optical properties of phthalocyanine (fluorescence and thermoluminescence) of hybrid materials were investigated. Finally, tests of material photostability under the influence of high-energy radiation were carried out with emission measurement in the ultraviolet and visible range. The aim of this study was to optimize the conditions for obtaining hybrid material containing phthalocyanine for potential application in optoelectronic systems, such as, photodiodes.
