Making equal-size colloidal quantum dots

Quantum dots (QDs) are semiconductor particles only a
few nanometers across that, thanks to their small size, exhibit
peculiar optical and electronic properties due to quantum
mechanics. With existing and foreseen applications in screens,
lighting, lasers, and energy harvesting, research in quantum dots
has been steadily progressing. In particular, colloidal QDs (CQDs)
have been in the nanotechnology spotlight for over a
decade.
