Low- and room-temperature phosphorescence characteristics of some pharmaceutical compounds.
Phosphorescence spectral characteristics, lifetimes and limits of detection of 30 pharmaceutical compounds are examined. A particular study on eight phenothiazine derivatives is carried out. Low and room temperature data obtained using an ethanol:water 80:20 glass substrate and a filter paper substrate, respectively, are compared. Lifetimes are corrected for the time constant of the measurement circuit.
