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 ....
