Self-organized CdSSe quantum dots thin films.
Self-organized and strained CdSSe quantum dot (Q-dot) thin films have been grown on ITO-coated glass substrates by novel wet chemical route. The Q-dots are (002) oriented faceted pyramids with average particle size of 7.5 nm. The X-ray diffraction results reveal the formation of a solid solution of CdSSe. Atomic force microscopy is used to investigate the morphology of the nanocrystalline thin films. The energy dispersive X-ray analysis spectrum confirms the presence of Cd, S, and Se in the films. Optical absorption and photoluminescence spectra show the blue shift for quantum dot thin films.
