Abstract
The photoluminescence of Er3+ ions in thin films of amorphous silicon has b een studied under conditions of intense pumping. A superlinear increase in the amplitude and a shortening of the photoluminescence relaxation times ar e revealed at a pumping intensity above 200 kW/cm(2). The data obtained are explained by the threshold ''switching-on'' of the superluminescence mecha nism. (C) 2000 MAIK "Nauka/Interperiodica".
