摘要：

The S3 centre occurs in natural type I diamond and consists of a strong luminescence band with zerophonon line at 2.496 eV. A detailed analysis of this centre shows that the low temperature luminescence originates in a spin forbidden transition. On increasing temperature a level 125 meV above the former becomes populated and a new luminescence band appears due to a spin allowed transition. No temperature dependent non-radiative processes were found up to room temperature. This centre reveals interesting characteristics that provide tunable stimulated emission in the range of 2.4-2.1 eV. © 1990.
