Method of forming a quantum dot structure.

摘要

A method of forming a quantum dot structure on a substrate (10) and devices incorporating such quantum dot structures are described. A suspension (11) of particles (12) of a semiconductor material for forming a quantum dot structure is formed, for example as a colloid by using the so-called arrested precipitation technique, and laser electromagnetic radiation (L) of a wavelength which interacts resonantly with particles (12a) of a given size is directed through the suspension (11) towards the substrate (10) so causing particles (12a) of the given size within the suspension (11) to be deposited onto the substrate (10).
