NVCore™ Premium

HPHT-Engineered Single-Crystal CVD Diamond with Ensemble NV Centers

NVCore™ Premium is a high-performance single-crystal CVD diamond platform engineered for ensemble nitrogen-vacancy (NV) applications requiring improved optical uniformity and a more controlled defect environment. Starting from nitrogen-containing CVD diamond, NVCore™ Premium undergoes an additional HPHT treatment designed to engineer the defect landscape and improve the uniformity and reproducibility of ensemble NV response.

The material features a typical nitrogen concentration of approximately 10–30 ppm in a polished (100)-oriented single-crystal diamond platform. Compared with standard NVCore™ Ensemble material, NVCore™ Premium is engineered to achieve a more optimized defect population rather than simply increasing the total nitrogen content. The Premium grade is intended for applications where strong ensemble NV response, reduced sample-to-sample variation, and reproducible optical and spin-defect behavior are important.

NVCore™ Premium is supplied in a typical 2 × 2 × 0.5 mm format with double-side polished surfaces, AFM roughness below 5 nm, full-corner geometry, and controlled crystal orientation. The additional HPHT processing distinguishes this grade from standard ensemble material by further modifying the nitrogen and vacancy defect populations following CVD growth.

NVCore™ Premium is particularly suited for:

• High-performance ensemble NV sensing

• Magnetic-field sensing and imaging

• Wide-field NV microscopy

• High-signal fluorescence measurements

• ODMR and spin-defect spectroscopy

• Quantum sensing research

• Studies of HPHT-mediated defect engineering in diamond

Product Selection Guideline

Choose NVCore™ Ensemble for nitrogen-rich CVD diamond with a high-density ensemble NV population and NVCore™ Premium has lesser number of nitrogen but better N to NV center conversion, it is ideal when a more engineered and reproducible ensemble NV response is desired. Choose OptiCore™ for general optical and spectroscopy applications, and QuantumCore™ Ultra for ultra-pure diamond intended for custom defect engineering, electronics, and quantum sensing research.
