Luminescence of the thallous ion in aqueous solution
Abstract
The luminescence of the thallous ion in aqueous solution has been studied using time-resolved spectroscopy over the concentration range, 10–4–10–2 mol dm–3. A general kinetic scheme is derived to fit the experimental data and it is shown that the emission does not arise from the initial excited species. A specific mechanism based on thallium ion–water excimers is proposed which is consistent with the experimental data.
