电沉积温度对碘化亚铜薄膜光学性质的影响
Influence of Deposition Temperature on The Optical Properties of CuI Thin Films
摘要
Abstract
Highly oriented γ-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 μm 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.关键词
