||The goal of this project is to create a UV sensor for use as a flame detection system in gas
turbine engine applications. In many gas-turbine engines, unnecessary engine shutdowns arise from
sensors failing to detect the engine flame because of deep films of oil and/or water that block the
sensor. In the infrared- and visible-light regions of the optical spectrum there is limited
penetration through oil/water mixtures. A UV sensor is to be designed that will be able to robustly
detect flames through oil/water mixtures that may build up on lenses in the gas turbine engine.
Zinc oxide (ZnO) nanowire arrays have been identified as a promising approach to developing a harsh-
environment UV sensor because of their ease of preparation, tunability of optoelectronic properties,
and inexpensive and scalable device fabrication methods.
