Sensor layers and waveguide layers produced in sol-gel technology

摘要

The paper presents the results of investigation studies on the application of sol-gel technology for the production of sensor layers and waveguide layers for the systems of planar waveguide sensors. The sensor layers are made up by silica SiO_2, which is playing the role of a matrix fixing bromocresol purple. These layers are sensitive to ammonia. The waveguide layers are produced in a two-component system SiO_2:TiO_2.
