Color Center Diamond Material General Description:

The Color Center Diamond, primarily featuring nitrogen-vacancy (NV) centers, represents an engineered single crystal diamond with unique quantum properties. These NV centers are atomic-scale defects consisting of a nitrogen atom adjacent to a vacancy in the diamond lattice. Negatively charged NV centers exhibit excellent spin coherence properties, making them ideal for quantum information science, sensing applications, and fundamental physics experiments.

Photonics On Crystals provides high-purity single crystal diamonds with controlled NV concentrations. The manufacturing process utilizes advanced doping techniques to achieve uniform NV distribution. Depending on specific requirements, NV densities are available in two configurations: DNV-B1 (low-density) and DNV-B14 (high-density). These materials are optimized for precision sensing, enabling groundbreaking advancements in quantum communication, magnetometry, and strain field detection.

 General Applications and Examples:

The Color Center Diamond finds extensive use in:

  1. Quantum Communication: Ideal for secure data transfer and quantum cryptography systems, where NV centers serve as qubits.
  2. Quantum Computing: Provides long coherence times and stable quantum states for scalable computing technologies.
  3. Magnetometry: NV centers enable highly sensitive magnetic field measurements for material characterization and biomedical diagnostics.
  4. Temperature and Pressure Sensing: High sensitivity in extreme environments, such as oil exploration or space instrumentation.
  5. Photon Detection and Imaging: Advanced photon generation and manipulation for next-generation imaging systems.

Example Use Case: In secure quantum communication, high-density NV-doped Color Center Diamonds ensure stable and reliable quantum state transmission over long distances. For magnetometry, low-density NV configurations achieve ultra-sensitive field detection in biophysical and industrial applications.

  • Adhesion Test Compliant with MIL-C-675C military standards, an adhesion test involved applying a tape that meets LT-90 specifications onto the lens film layer. The tape was affixed fully and then removed vertically. This procedure was performed three times, resulting in no blistering or peeling.
  • Temperature Test In line with MIL-C-675C specifications, test pieces were subjected to temperatures of -62±1℃ and 71±1℃. After maintaining them at room temperature (16℃~32℃) for two hours, the adhesion test was repeated, confirming no film detachment.
  • Abrasion Resistance Test Conforming to MIL-C-675C and CCC-C-440 standards, the abrasion resistance test involved a gauze tester applying a minimum force of 1.0 lbs (0.45 kg) to the film. This was repeated 25 times with gauze widths of 1/4 inch (6.4mm) and 3/8 inch (9.5mm), ensuring no damage occurred to the film surface.
  • Humidity Test Under MIL-C-675C criteria, the test piece was placed in a controlled temperature and humidity chamber set to 49 ±2℃ and 95%~100% humidity for 24 hours. The film remained intact, with no peeling, scratches, or other defects.
  • Solvent and Cleaning Testing Following MIL-C-675C specifications, test pieces were exposed to room temperature conditions (16℃~32℃) and tested with acetone and alcohol for at least 10 minutes each. After air drying and subsequent cleaning with a cotton cloth soaked in alcohol, the film surface showed no signs of peeling or scratches.
  • Salt Spray Test After 100 hours in a 35°C environment with a 5% saltwater concentration, the film showed no signs of damage.
