 What is Fluorescent Nanodiamond (FND)?

  • FNDs are tiny diamonds made from carbon nanoparticles, produced under high temperature and pressure.

  • They are non-toxic and stable under light, making them suitable for various applications, especially in biology for tracking cells.


Fluorescence Properties

  • FNDs exhibit fluorescence, emitting light of lower frequency when exposed to higher frequency light.

  • They have a long fluorescence lifespan (over 10 nanoseconds), which is advantageous compared to other nano-fluorescent materials like quantum dots.


Recent Experiment

  • Researchers at Purdue University levitated FNDs in a vacuum and spun them rapidly, demonstrating their potential for industrial applications, particularly in sensing technologies

Quantum Spin and Berry Phase

  • Spin is a fundamental property of particles like electrons, existing in two states: up and down.

  • The Berry phase, related to the wave properties of particles, can be measured through the rotation of FNDs, revealing new insights into quantum effects and materials.


Applications in Industry

  • FNDs can be utilized as sensitive sensors for acceleration and electric fields, making them valuable in high-tech industries.

  • They may be developed into gyroscopes for precise rotation sensing 

  • Can be doped with nitrogen to enhance their properties, allowing them to produce quantum effects for advanced computing and sensing applications.
