Influence of Deposition Temperature on The Optical Properties of CuI Thin Films
Highly oriented -CuI thin films have been successfully prepared on indium doped tin oxide (ITO) glass substrate by a simple electrochemical process at different temperatures. For comparison
CuI powders are also obtained by a simple complex compound method. Analyses on phases and structures based on X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) techniques indicate that the films are composed of CuI triangular facet nanocrystals with (111) preferred growth orientation
and decrease from 2 m to 500 nm with increase of the deposition temperature. Furthermore
photoluminescence (PL) spectroscopic analysis shows a strong near band edge emission. It is also found that the CuI powders show some diverse in structural
morphology and optical properties compared with the CuI thin films.
