Nanomaterials Simulator – Quantum Dots & Nanoparticles
Nanomaterials exhibit properties dramatically different from bulk materials because quantum-mechanical and surface-area effects dominate at the 1–100 nm scale. This simulation lets you manipulate size and shape of quantum dots and metal nanoparticles, then observe how optical, electronic, and catalytic properties shift with the quantum-confinement effect.
What you can do in this simulation
- Adjust quantum dot size from 2 to 10 nm and observe the blue-shift in bandgap and emission color
- Compare surface-area-to-volume ratios at different nanoparticle sizes and link to catalytic activity
- Visualize fullerene (C₆₀), carbon nanotube, and graphene structures and their bonding patterns
- Explore localized surface plasmon resonance of gold nanoparticles as a function of diameter
- Investigate how nanoparticle shape (sphere, rod, cube) affects optical and electronic properties
Concepts covered
quantum confinement · bandgap tuning · surface plasmon resonance · surface-area-to-volume ratio · carbon allotropes · nanoparticle size effects
