Description
NVCore™ Ensemble
Nitrogen-Rich Single-Crystal CVD Diamond with Ensemble NV Centers
NVCore™ Ensemble is a single-crystal CVD diamond engineered for applications that benefit from a high density of nitrogen-vacancy (NV) color centers. The material combines ppm-level nitrogen incorporation with a polished (100)-oriented diamond platform, providing a practical starting point for ensemble NV fluorescence, ODMR, magnetic-field sensing, imaging, and quantum sensing research.
Unlike ultra-high-purity electronic-grade diamond, NVCore™ Ensemble is intentionally nitrogen rich, with a typical nitrogen concentration in the approximately 10–30 ppm range. This higher nitrogen content supports the formation of a dense ensemble of NV-related color centers, enabling stronger optical signals over larger sensing volumes than low-defect quantum-grade hosts.
Standard NVCore™ Ensemble crystals are supplied as single-crystal CVD diamond, typically in 2 × 2 × 0.5 mm format, with (100) orientation, polished top and bottom surfaces, and full-corner geometry. The characteristic brown coloration reflects the nitrogen-rich defect environment of the diamond.
NVCore™ Ensemble is particularly suited for:
- Ensemble NV fluorescence and ODMR measurements
- Magnetic-field sensing and imaging
- Wide-field NV microscopy
- Spin-defect spectroscopy
- Quantum sensing proof-of-concept studies
- Education and research involving NV-center physics
- Studies of nitrogen incorporation, vacancy formation, and defect-engineered diamond
Because NVCore™ Ensemble is designed around a relatively high defect density, it prioritizes ensemble optical signal and NV population rather than the exceptionally low spin-bath environment required for long-coherence single-NV experiments. For applications requiring ultra-low nitrogen backgrounds and user-controlled NV formation, an electronic-grade diamond host would be more appropriate.
Product selection guideline
Choose NVCore™ Ensemble or NVCore™ Premium for ready-to-use ensemble NV centers, OptiCore™ for general optical and spectroscopy applications, and QuantumCore™ Ultra for ultra-pure diamond intended for custom defect engineering, electronics, and quantum sensing research.
NVCore™ Premium is intentionally nitrogen-rich and optimized for high ensemble NV activity rather than single-NV coherence.
