| Abstract: | The absorption constantK of amorphous As2S3 was determined at the absorption edge in the range 1 to 105 cm–1. It is shown that at low energy levels up to about 103 cm–1
K depends exponentially on the photon energy; at higher absorption levels the energy dependence ofK is quadratic. The significance of these results is discussed. When sulphur is added to As2S3 the absorption edge has similar properties but is shifted towards lower energies. |
