Chapter 21, Problem 21.12CP

Interpretation Introduction

Interpretation:

Using the relationship between nanoparticle size and band gap, determine which particle size corresponds to which energy diagram.

Concept introduction:

• Quantum dots are examples of semiconductor nanoparticles whose colours vary with the diameter of the particle.
• On the nanoscale, both particle size and chemical composition affect the properties as different sized quantum dots exhibit different colours.

To classify:

The energy diagram that corresponds to each nanoparticle.
