Amorphous silicon carbide may be doped with one or more ions such as vanadium and these ions may radiate light if excited, for example, using optical or electrical pumping. A single photon light source may be formed from a single such ion that is pumped or from a plurality of ions that are pumped if light from only one ion is collected, e.g., using an aperture or pin hole. Such single photon sources may possibly be use in quantum computing, quantum sensing and/or quantum telecommunications.

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.

Methods of synthesizing transition metal dichalcogenide nanoparticles include forming a metal-amine complex, combining the metal-amine complex with a chalcogen source in at least one solvent to form a solution, heating the solution to a first temperature for a first period of time, and heating the solution to a second temperature that is higher than the first temperature for a second period of time.
