Abstract
The spectra of light emission from a separate emission center in porous sil icon contained in "sandwich" structures were measured under the passage of electrical current as a function of applied voltage. The light intensity in creases quicker in the short-wave part of the spectrum than in the long-wav e part on increasing the voltage. Such a feature of the spectrum change has been observed earlier for island metal films. (C) 2001 Elsevier Science B. V. All rights reserved.
