Quantum effects arise when particles shrink. As the size of a material is reduced to the nanoscale, the electronic and optical properties become dependent on the size and shape of the nanostructure.

What is the Quantum Size Effect? The quantum size effect (QSE) is a phenomenon observed in nanomaterials where their electronic, optical, and magnetic properties deviate from those of the bulk ...

Their size-dependent colors are essentially a naked-eye, ambient-condition visualization of the quantum confinement effect. In recent years, more exotic quantum effects have been observed using ...
