Abstract

Chapter 8 describes some potential portable explosive sensors based on organic polymers. A CMOS lifetime micro-system, developed at the University of Edinburgh, can measure nanosecond time-scale PL decay. This is adapted as a tool for trace explosive detection. The vapour molecules reversibly quench the light emission from the copolymer CDT Green and change the PL decay lifetime. The integration of the micro-LEDs as optical excitation, the CMOS micro-system as detector, and the organic semiconductor as sensing element, promises an inexpensive and ultra-portable explosive detector. At the end of the chapter, a compact LED-pumped BBEHP-PPV laser is also used for the detection of low vapour pressure explosives with very fast responsivity.
