In this study, we investigate the third-order nonlinear optical properties of phenol red (PR) solutions and their hybrid composites, analyzing a PR solution with a pH of 7.56, a zwitterionic PR solution (PRz) with a pH of 1.52, and a PR-doped PVA/silica (PR-PS) hybrid composite made using an acid-ca...
