Examples

  • In mid-2010, Dr Turnbull and his team developed laser technology able to sense hidden explosives by "pumping" a type of plastic called polyfluorene with photons from another light source.

  • The laser sensor, developed by physicists from the University of St Andrews in Fife, Scotland, relies on the fact that when a type of plastic called polyfluorene is "pumped" with photons of light from a light source it emits laser light.

  • Graham Turnbull, a physicist at the University of St Andrew's in Fife, UK, and colleagues have developed a device that uses a film of polyfluorene, a plastic that emits laser light when bathed in photons.

    New Scientist - Online News

  • Dr. Turnbull said that while similar techniques using organic semiconductor lasers had been looked at before, this is the first time scientists have used a polyfluorene laser, and its use enables much lower concentrations of vapors to be detected.

  • The same electron-transfer effect occurs with the new polyfluorene laser.

  • After 4-5 minutes the response had slowed and then flattened off, which the researchers suggest is due to the vapor molecules interacting with the surface of the polyfluorene.

  • The plastic polyfluorene is a cheap material, which is an obvious advantage for a device designed to detect explosives.

  • Using a thin film of polyfluorene (essentially a light-emitting plastic) the group has created a laser that reacts with vapours from explosives.
