Solution
The correct option is C Both 1 and 2
Explanation:
Both statements are correct
- Quantum Dots are semiconductor nanoparticles that glow a particular color after being illuminated by light. The color they glow depends on the size of the nanoparticle. When the quantum dots are illuminated by UV light, some of the electrons receive enough energy to break free from the atoms.
- This capability allows them to move around the nanoparticle, creating a conductance band in which electrons are free to move through a material and conduct electricity.
- Quantum dots are both photoluminescent and electro-active and hence find their most common use nowadays in display screens.
