Effects of viscosity and refractive index on the emission and diffusion properties of Alexa Fluor 405 using fluorescence correlation and lifetime spectroscopies
(Springer, 2021-03-19)Fluorescence Correlation Spectroscopy (FCS) studies of the interaction of polymers or proteins in solution are strongly affected by the viscosity and refractive index of the medium, and the effects are likely to be more ... -
Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor
(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
(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
(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 ... -
Time-Resolved Fluorescence Spectroscopy of Crude Petroleum Oils
(2009-03)Characterisation of crude oil properties in real-time by spectroscopic methods has been a major challenge to the oil industry. While current methods can show the presence of oil, a quantitative determination of oil ...
