Recently, Rajamathi and Seshadri [65] have reviewed the uses of solvothermal methods for the preparation of oxide and chalcogenide nanoparticles. For oxide nanoparticles, these methods can involve hydrolysis, oxidation and thermolysis, all performed under hydrothermal or solvothermal conditions. Some of the more striking examples are provided here.

Metal chalcogenide aerogels prepared by condensation of metal chalcogenide nanoparticles (quantum dots) exhibit unique optical properties. What are these properties and how does the aerogel dimensionality determine the extent of quantum confinement You may wish to consult Chapter 16 on semiconducting nanoparticles in answering this question.

From a theoretical point of view, the understanding of chalcogenide nanoparticles, particularly that of Ru Se, whose stoichiometry, from the solvent synthesis, always led to x 2 and Se 1, requires (semi-) infinitely extended surfaces and a thermodynamic equilibrium. This length and time scale allowed obtaining some interesting information about the particle environmental conditions using DFT calculations [31]. Indeed, under the condition > ) ru + 2/tsg, the...

Recently, we have further explored new single source molecular precursor (SSMP) for the preparation of chalcogenides nanoparticles. CdSe nanoparticles are successfully prepared by solvent less pyrolytic route using Cd(II) complex of Bis(aminopropyl) selenide, CdTe nanoparticles were synthesized using Cd(II) complex of Bis(aminoethyl) telluride and ZnSe by Zn(II) complex of Bis(aminoethyl) selenide. Basic features of synthesis and some characterization of synthesized nanoparticles are presented here. The details will be presented elsewhere [274].
