Quenching of the luninescence of the aqueous gadolinium ion by nitrate and thiocyanate
Abstract
The emission from the lowest sextet of the aqueous gadolinium ion is found to be strongly quenched by nitrate and thiocyanate. The influence of ionic strength, temperature, viscosity and a strong complexing agent such as EDTA, have been investigated. Quenching occurs by an electron-exchange energy-transfer mechanism.
