Abstract
The method of preparation of electroluminescent (el) cells using dielectric liquids like castor oil and liquid paraffin by an electroforming process is presented. Theel spectrum of the material derived from castor oil exhibits a large number of sharp lines which can be grouped into four distinct series superposed on a broad background. Theel spectrum of liquid paraffin cells does not show any significant line features. The N2 laser excited fluorescence spectra of these oils and of the respective electroformed materials are also recorded. The electrical and brightness characteristics of these cells are discussed in detail.
