Quantum Dots Explained ✍️ 

Quantum dots are tiny particles of a special kind of material called a semiconductor. They are so small that they behave differently from normal materials. They can absorb and emit light of different colors depending on their size and shape.  

You can think of quantum dots as artificial atoms that can be made in a lab! They have some of the same properties as atoms, such as having discrete energy levels (meaning they can only exist in certain distinct energy states, and they cannot have energy values between these specific levels) and being able to form molecules with other quantum dots. But they also have some unique features that make them useful for many applications, such as displays, solar cells, sensors, and medicine.
