  • Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor 

    Ryder, Alan G.; Power, Sarah; Glynn, Thomas J. (2003)
    We report a novel fluorescence-lifetime-based pH sensing method that utilizes acridine incorporated into Nation (AcNaf) as the fluorescent indicator. The AcNaf sensor is excited using a 380 nm light emitting diode (LED) ...
  • Frequency domain fluorescence lifetime study of crude petroleum oils 

    Owens, Peter; Ryder, Alan G.; Blamey, Nigel J. (Springer Verlag, 2008-02-01)
    Frequency domain (FD) fluorescence lifetime data was collected for a series of 20 crude petroleum oils using a 405 nm excitation source and over a spectral range of similar to 426 to similar to 650 nm. Average fluorescence ...
  • Low Temperature Fluorescence Studies of Crude Petroleum Oils 

    Owens, Peter; Ryder, Alan G. (2011)
    We have studied the low-temperature (133-298 K) fluorescence emission of crude petroleum oils using a combination of steady-state and time-resolved measurements. This was done, first, to see if we could generate linear ...
