The sensor coatings developed by SCS are based on integrating phosphor materials into functional coatings. The principle of phosphorescence is covered here. Essentially it is a process whereby light is used to excite the material and as a result light of a different wavelength (colour) is emitted. The emitted light can be analysed to give important information about the state of the material.
These types of materials, often called phosphors, can be found in energy-efficient lighting, plasma screens and LEDs.
