Sol-Gel Properties for Fiber Optic Sensor Applications

This work reports a discussion of several sol-gels formed using a variety of preparation procedures with a view to the production of a suitable substrate for chemically sensitive dyes for various fiber optic fluorescence-based sensor applications. The compositions, qualitative appearance, and coating abilities of a series of gels are discussed, as is their suitability as substrates for indicator materials for the sensor purpose in view.
