Modified top-down approach for synthesis of molybdenum oxide quantum dots: sonication induced chemical etching of thin films.

A simple and modified top-down approach to synthesize molybdenum oxide (MoO : = 2, 3) quantum dots (QDs) is proposed in this study. This modified approach involves the conversion of a bulk powder material into thin films followed by a sonication induced chemical etching process for synthesising QDs. X-Ray Diffraction (XRD) is used for crystal structural characterization of MoO thin films.
