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.
