Quantum Dots and Colors
Each group needs:
- cardboard shoe box
- black light bulb (such as Smart Electric 60W A19 black light bulb, model #110 for $5.02 at The Home Depot)
- desk lamp compatible with A19 type bulb (suitable lamps may be available in school labs)
- black construction paper, 4 sheets
- test tube holder (or similar fixture) for holding quantum dot vials
- stopwatch
- Quantum Dots and Colors Worksheet, one per student
To share with the entire class:
- quantum dots of various particle sizes (obtain a minimum of three different particle sizes; see suggested sources listed below, such as LumidotTM quantum dot kits, which include various size ranges for demonstrations)
- 2 packages of 50, 9 x12-inch black construction paper ($1.49/pack, available at Office Depot)
- masking tape and marker, to label vials with particle size of solution
- tape (or glue)
- scissors
Three source options for quantum dot solutions:
- CDSe 5 ml solutions individually purchased for $194 per 5 ml solution, such as part #662429 at SigmaAldrich https://www.sigmaaldrich.com/
- LumidotTM CDSe-6 quantum dot nanoparticles kit for $687, such as #662593-1KT at SigmaAldrich https://www.sigmaaldrich.com/
- Contact a local university biochemistry or chemistry program to request sample quantum dot solutions for classroom use; ask for a minimum of 5-10 ml per solution per group
