Electrochemiluminescence on Dy(III) and Tb(III)-doped Al/Al2O3 surface electrode

Electrogenerated chemiluminescence of chosen terbium complexes deposited into Al2O3 layer at the aluminium cathode

“…ECL studies were carried out using specially constructed device designed for the registration of the weak light emission and analysis of its spectral distribution [4,6]. The experimental setup have been incorporated a Hamamatsu R-636 photomultiplier tube in ''light-tight'' box, cooled to À15 1C and monochromator JOBIN YVON TRIAX 180.…”

“…The methods: classical ECL [1] and the cathodic pulse electrochemiluminescence (ECL) have been used in the studies of mechanisms and quantitative analyses of various systems, including lanthanide complexes and biologically active compounds in water solutions [2][3][4][5][6]. The primary step of cathodic generation of ECL is an injection of tunnel-emitted hot electrons into the conduction band of water, which probably also results in the generation of hydrated electrons from these presolvated hot electrons by thermalization and solvation [7].…”

Electrogenerated luminescence of chosen lanthanide complexes at stationary oxide-covered aluminium electrode

“…ECL measurements were carried out using the experimental setup described earlier [5]. The detection module of this setup allows the recording of emission (chemi-and electrochemiluminescence) spectra with a standard resolution of a moderate quality spectrofluorimeter.…”

“…Electrogenerated chemiluminescence (ECL) leads to the production of light at or near the electrode surface by generating species capable of forming excited states of organic ligands. If energy transfer from these excited organic ligands to the complexed metal centers occurs, characteristic emissions from the central lanthanide ions can occur [3,5]. In the case of electrogenerated chemiluminescence induced by hot-electrons, ligand sensitised redox excitation of the lanthanide complexes is mainly observed.…”

Hot Electron Induced Cathodic Electrochemiluminescence at Disposable Screen Printed Carbon Electrodes

“…The thin insulating film plays a key role in the ECL process, making the tunnel emission of energetic electrons possible [3]. To the best of our knowledge, Al/Al 2 O 3 [4], Si/SiO 2 [5], as well as highly doped semiconductor electrode coated by MgO thin films [6] were reported to be tunnel emission electrodes for generation of cathodic ECL. However, these electrodes can not be used in strong basic and/or acidic condition, in which such thin oxide films are quite fast dissolved [7].…”
