Abstract:
Nano-sized terbium(III)-phthalic acid complex was prepared in polyvinylpyrrolidone. It's fluorescent spectrum has been investigated, compared to that of common terbium(III)-phthalic acid complex and terbium(III)-polyvinylpyrrolidone complex. The results show that fluorescent characterizations of Nano-sized terbium(III)-phthalic acid complex is obviously different from that of common terbium(III)-phthalic acid complex and terbium(III)-polyvinylpyrrolidone. The relative intensity and half-height width of main emission peaks are obviously varied, two splitting peaks are displayed.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
