Basics of Nanoscale & Quantum Dots
Nanotechnology operates at dimensions where matter shows entirely new properties. Quantum dots represent a crucial nanoscale innovation, enabling precise control over light and electrons, with growing relevance for India’s healthcare, energy, electronics, and advanced manufacturing ecosystems.
Core Concept
- Nanoscale refers to structures sized between 1-100 nanometres, where physical and chemical properties differ from bulk materials.
- Quantum dots are semiconductor nanoparticles whose electronic and optical behaviour depends on their size.
How the Technology Works
- At the nanoscale, reducing material dimensions increases surface effects and restricts electron movement.
- In quantum dots, electrons are confined in all directions, creating discrete energy levels.
- By ....
