What is Phosphor Thermometry ● Phosphor thermometry is an optical method for surface temperature measurement. ● Phosphors are fine white or pastel-colored inorganic powders which efficiently emit light. Certain characteristics of the emitted light change with temperature, including brightness, color, and DECAY TIME. The latter is most commonly used for temperature measurement. ● A thin layer of phosphor is applied to the surface whose temperature is of interest.

Typical Phosphor Characteristics ● Inert and in some cases they are ceramics ● Easily applied by paint or air brush – in other instances by plasma or E-beam deposition ● Emit light in narrow band which may fall anywhere from the mid-infrared to the ultraviolet. Most thermographic uses have been using visible emitting phosphors ● Decay time may range from a few nanoseconds to minutes.

Phosphors for Engine Health Monitoring ● Phosphors can also be used for Engine Health Monitoring – Thermal barrier coatings (TBC) can be coated with a Phosphor and then inspected after operation to determine the health of the TBC – This can be done in a test cell environment or could eventually be use as a maintenance inspection for verifying TBC condition – The Air Force is considering developing and using the Phosphors for this purpose
