Ensemble NV Diamond 111

Ensemble NV diamond (ENV-20) contains a high density of NV centers. It is pink due to the high density of NV center.
NV center is an atomic-level sensor. The ultimate sensitivity of the diamond is determined by the density and coherence time of NV centers.
ENV-20 diamond is a high-quality quantum-grade diamond that contains high density and high spin coherent NV centers. It is primarily used in fields requiring high-sensitivity detection.

This is our ensemble NV diamond with polished faces {100}, {110}, {111}.

HaiNan Neocrystech Co., Ltd. offers quantum-grade diamond products that contain deliberate and controlled levels of nitrogen-vacancy (NV) centres, including high-quality single and ensemble NV centres.

Our exclusive production features an internally dispersion of single NV centers (SNV) in a density between 10 and 300 per 10000 µm², with typical spin coherence times (T2) exceeding 300 µm and a long T2* of 1~3 µm. We support for customization in single NV density, diamond size, and preferred polished faces {100},{111} or {110}.

Our ENV diamonds contains high density NV centres varying from 500 ppb to 5 ppm, with T2 ranging from 100 to 200 µm and T2* of 0.5 µm. We offer customized diamonds with major {100},{111} or {110} in different densities.
