Quantum Dot Demonstration

Included in your kit is a guide with directions and information on how nanotechnology is involved.

In this demonstration you will explore how material acts differently when its particles are nanometer-sized!

Each vial contains particles of different nanometer sizes. Each LED light is a different color, meaning they have different wavelengths.

Start by shining the red light onto each vial. You may point the light directly at the vials or hold them underneath to illuminate from the bottom.

What do you notice? Is this what you expected?

What do you notice about the lights of smaller wavelengths? What do you see in the center of the vials?

What's going on? Check the guide here.
