A comparative study, luminescence behavior of 6-Mercaptopurine (6-MP), Azathiopurine (BAN), and 8-Azaguanine (8-Azan) have been investigated including the low temperature phosphorescence, the low temperature fluorescence, the room temperature phosphorescence (RTP) and the room temperature fluorescence (RTF). The effect of pH on the luminescence intensity is(More)
The luminescence behavior of diiodofluorescein (DIF) and tetrabromofluorescein (TBF) have been investigated including the solid surface room temperature phosphorescence (SS-RTP) and the room temperature fluorescence (RTF). The luminescence intensities of the two compounds are strongest in alkaline solution. RTP lifetime of the two compounds are in the range(More)
