Abstract

For the fundamental studies of gas reception there is a need in materials that (i) have well-defined morphology with only type of surfaces exposed to ambient gas and (ii) preserve same morphology over different length scales 1. The size- and shape- controlled nanocrystals of sensing materials with controlled surface properties will not only allow for separation of so-called “smoothly scalable” size-dependent properties from qualitatively new effects appeared as particle size decreases, but also will provide control over gas sensing activity in nanosensors. The latter can be achieved either through management over reception as that in well-controlled {012} rh-In2O3 nanocrystals 2 or through the synergy of inorganic and organic functionalities as that in hybrid self-assembled organotin thin films 3. The first step toward such nanomorphological control is the design and synthesis of well-defined nanocrystals which are uniform in size, shape and structure; such materials are ideal candidates for fundamental studies of mechanisms of gas sensing.
