Quantum just means very small.
A quantity so tiny,
electrons in its atoms will
behave constrained and tidy.

Quantum Dots are very small.
They’re nano-sized or less.
When energized by radiant light,
they vividly fluoresce.

Many modern TV screens
now use such Quantum Dots,
creating glowing hues for scenes
from brightly coloured spots.

Carbon Dots fluoresce in red.
If silkworms on those dots are fed,
they’ll glow in daylight – not in red …
their skin and silk glow PINK instead!
