The thesis describes the development, characterization and application of fluorescence-based, optical pH sensors. Special attention is given to the dependence of the sensor signal and changes of ionic strength in the analyte solution. Based on three different methods for minimization of this dependence, various sensor membranes are presented in detail. Further, a new concept to reference fluorescence intensity signals is introduced and applied to an optical pH sensor. Chapter 1 emphasizes the necessity of precise pH control and measurements by means of examples. An overview of possible fields of pH sensors is given in general. In particular, three different formats of optical pH sensors are presented. Furthermore, the cross-sensitivity of ...
