Abstract
The analysis of spatial photoluminescence distribution along a plate from synthetic diamond as grown at 1500°C allowed us to study a sequence of formation of nitrogen-nickel optically active centers and to build maps in some cases. Several groups of vibronic systems with specific spatial distribution along the sample were separated: nitrogen-vacancy pairs in the thin near surface layer, low-temperature centers with blue emission, nickel-nitrogen complexes with a single nickel ion and those with several nickel ions.
