We have found that several nitrogen-related luminescence centers appear at 389 nm, 503 nm (H3 center), 575 nm (NV0 center), 637 nm (NV- center) in single-crystalline Ib diamond cut by means of a YAG laser irradiation process, followed by a suitable h

We have grown a high-quality type-IIa single-crystal diamond substrate, which had a large (001) growth sector with a dislocation-free area of 3.5 × 3.5 mm2, and strong free exciton (FE) emissions were observed by cathodoluminescence (CL), while disl
