✦ Synopsis
The dc electroluminescence of cations in inorganic liquid solutions is due to the injection of electrons from the Femd level of the cathode into the positive double layer. The layer facilitates eIectron escape by a Schottky effect and acts as a potential well, The electroluminescence provides a tool for the study of the dynamics and the structure of double layers Solutions of Tb* ions electroluminesce in phosphoros oxychloride POCK, when a dc'potential in excess of 5.5 V dc is applied to immersed electrodes. The spectrum of electroluminescence is similar to the photoluminescence spectrum of Tb3+ in phosphorus
