摘　　要：The relation of the electrochemiluminescence(ECL) intensity with the shape of perforated and imperforated platinum electrodes has been investigated. ICCD(Intensified charge coupled device) was used to get the images of ECL of Ru(bpy) 3 Cl 2 ·6H 2 O and tripropylamine(TPA) on the electrodes. The results showed that the ECL was concentrated on the edge of the electrode. For the perforated platinum electrode, the ECL intensity was found to be dependent both on the electrode edge and the edge of the holes on the disk electrode. The ECL intensity of Ru(bpy) 3 Cl 2 ·6H 2 O measured on the four hole disk electrode was double higher than that measured on the simple disk electrode and the detection limit was increased approximately by three orders of magnitude from 1 fmol/L to 1 amol/L.The relation of the electrochemiluminescence(ECL) intensity with the shape of perforated and imperforated platinum electrodes has been investigated.
