ELECTROLUMINESCENCE IN SEMICONDUCTING DIAMOND AND ITS STIMULATION BY INFRARED.
Abstract
The blue electroluminescence (EL) of semiconducting diamonds was measured at 80K. It was found to be stimulated by irradiation of the crystal with infrared or visible light. The light-stimulated EL depended linearly on both the light intensity and the current, and its excitation spectra was found to follow that of the photo current. Application of an electric field across the crystal at 80K excited thermoluminescence TL, with the main glow peak at about 270K. Although infrared for itself did not excite TL at all, its application prior or simultaneously with the electric field was found to stimulate the TL. It is suggested that the infrared light raises valence band electrons to an intermediate energy level in the forbidden gap from which they are excited up to the luminescence centers by the electric field.
