abstract: This work investigated the effect of pH variation of carminic acid on the structural and fluorescence properties of a silica-based hybrid composite fabricated using the sol-gel method. Changes in the microstructural characteristics and the structural and fluorescence properties were investigated as the pH of the carminic acid varied from 2.5 to 12.0. The hybrid composite significantly enhanced the fluorescence intensity with a tendency to increase at higher pH values. Results also showed that the pH of carminic acid changed the structural arrangement of Si-O rings. Specifically, low pH values for the carminic acid favor the formation of four-membered Si-O rings, while high pH promotes an arrangement of six-membered Si-O rings. The close relationship between the structural and functional properties of silica and the ability to control these properties by changing the pH value of the dye could have a strong impact on its incorporation in the development of emergent technologies.
