Crystalline silicon nanoparticles (quantum dots) with diameters around 4 nm are produced via CO2-laser-induced decomposition of SiH4 in a flow reactor and subsequently transferred into a freely propagating cluster beam. Thin structured films are then obtained by shaping the beam with a mask and depositing the nanoclusters at low energy on a sapphire substrate. Upon illumination with ultraviolet radiation, the nanoparticles exhibit strong photoluminescence in the red.
