Are Quantum Dots Spherical? Identifying Size of Colloidal Solution

Click For Summary
SUMMARY

The discussion focuses on determining the spherical shape of quantum dots in a colloidal solution. The recommended method involves smearing the solution onto a glass substrate and capturing images using a scanning electron microscope (SEM). This technique allows for precise visualization and analysis of the quantum dots' morphology. The use of SEM is crucial for confirming the size and shape of the particles effectively.
