Methods of generating nanoparticles are described that comprises feeding nebulized droplets into a radio frequency plasma torch to generate nanoparticles, wherein the majority of the nanoparticles generated have a diameter of less than about 50 nm. These methods are useful for synthesizing nanoparticles of metals, semiconductors, ceramics or any other material class where the precursors are either in liquid form or can be dissolved or suspended in a suitable liquid. Methods of feeding nebulized droplets and central gas into a radio frequency plasma torch and apparatus for generating nanoparticles are also described.

A method for testing the quality of a solvent is disclosed. The method comprises obtaining a solvent sample, wherein the solvent sample contains less than 10 ppm of impurities and nebulizing the solvent sample thereby forming a multitude of droplets that comprises solvent and impurities. The method further comprises evaporating the solvent from at least a portion of the multitude of droplets to thereby form a multitude of aerosol particles, condensing a liquid onto at least a portion of the multitude of aerosol particles to a multitude of form liquid-coated aerosol particles, and counting the number of liquid-coated aerosol particles.

A solvothermal process for making inorganic nanoparticles is described. Inorganic nanoparticles can be produced by forming a suspension or solution comprising at least one group II-IV and lanthanide metal inorganic salt in a first medium, disposing the suspension or solution in a sealed chamber having an interior pressure, elevating the interior pressure of the sealed chamber to an initial interior pressure prior to the heating, heating the suspension or solution to a peak temperature higher than the normal boiling point of the first medium, optionally adding a second medium to the suspension or solution after the heating.
