Abstract: The monomeric phosphorescence bands(λem= 420 nm and 440 nm, λex= 290 nm) have heen observed in the luminescence spectra of the aqueous solution (1.0×10-4 mol/L) of N-vinylcarbazole and acrylic acid with Tl+([Tl+]=1.0×10-5-2.5 ×10-3 mol/L) at room temperature at pH=10. It is found tliat the relative intensities of the phosphorescence increased with increasing the concentration of Tl+.

Key words: Phosphorescence, Thallium ion, Copolymer of N-vinylcarbazole and acrylic acid
