Abstract
Doped nanoparticles, methods of making such nanoparticles, and uses of such nanoparticles. The nanoparticles exhibit a metal-insulator phase transition at a temperature of −200° C. to 350° C. The nanoparticles have a broad range of sizes and various morphologies. The nanoparticles can be used in coatings and in device structures.
Claims19
A VO2 nanoparticle doped with a plurality of metal cations selected from the group consisting of K cations, Na cations, Cs cations, Sr cations, Ba cations, Ca cations, W cations, Mo cations, Ag cations, Pb cations Nb cations, Cr cations, Al cations, Fe cations, Ti cations, Zr cations, Ta cations, Sc cations, Ga cations, Cu cations, Co cations, Ni cations, rare-earth element cations, and combinations thereof,
- wherein the dopant is present in the nanoparticle at 0.1 to 10% by weight,
- wherein the dopants do not segregate into distinct phases and the dopants are substitutionally incorporated within a VO2 structure such that they replace vanadium atoms in the VO2 structure;
- and
- wherein the nanoparticle exhibits a metal-insulator transition at a temperature of from −200° C. to 350° C.
