Electrogenerated luminescence in solution

摘要

A method whereby the presence and/or amount of a chemical moiety containing terbium is determined by applying an electrical pulse to an electrode immersed in a solution and measuring the delayed light emission after some time from the end of the pulse, said chemical moiety being either bound to said electrode and/or present in said solution and said emitted light being taken as an indication of the amount of the chemical moiety present in the proximity of said electrode.
