Quantum Dots and Colors

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and color wavelength.

Instructional Ideas

  • Spend some time with the class reviewing light wavelengths and their relationship to frequencies, along with how to calculate one given the other
Classroom Considerations

  • It is beneficial if the class understands the basics of wavelengths and frequencies
  • Each group needs a shoebox
  • The fifth segment in a series of six

  • The materials list gives suggestions on where to acquire the quantum dot solutions needed
  • Handout includes the background information 

  • Purchasing the quantum dot solutions may be expensive
