Abstract:

Layered Molybdenum trioxide M_OO₃, with a two-dimensional (2D) structure was successfully delaminated into colloidal nanosheets in n-butanol via a soft-chemical process involving intercalation of dodecylamine. X-ray diffration (XRD) showd that: after intercalation spacing of the layered material expend to 2.69nm from 1.38nm, and Characterizations by transmission electron microscopy (TEM) and scan electron microscopy (TEM) confirmed the formation of unilamellar 2D nanosheet crystallites with an average lateral size of 400 nm. The obtained nanosheets exhibited photochromic properties upon UV-VIS excitation. The chromogenic nanosheet obtained in this study features the intense UV absorption and optically switchable Visible-to-IR absorption, which may be useful for window applications such as heat-absorbing films.
