Becht, A. and Vogler, Arnd (1994) Photophysics and photochemistry of main group metals with an s² electron configuration. Luminescence quenching and photoreduction of trihydroxoplumbate(II) by hydroxide. Journal of Chemical Sciences 106 (3), pp. 639-643.
The luminescence of Pb(OH) 3 − in deaerated aqueous solution is quenched by hydroxide withk = 1.87 × 105 Lmol−1 s−1. It is suggested that this quenching is associated with an electron transfer from hydroxide to Pb(OH) 3 − in its3P1 sp-excited state. This assumption is supported by the photochemical behaviour of Pb(OH) 3 − which is photoreduced to metallic lead. The efficiency of the photolysis increase with hydroxide concentration.
