✦ Synopsis
The absorption and emission characteristics of 7-hydroxycoumarin (HCM) and 1-hydroxypyrene-3,6,8-trisulfonate (HPTS) have been studied in the water/oil microemulsion systems formed with AOT, BuOH, heptane, and decane as components. The absorption and emission features of HCM and HPTS have been correlated with the pH of buffer solutions to ascertain the pH of the oil/water interface and the interior of the water pool.
