A method of concentrating nanoparticles, having the steps of: adding and mixing an extraction solvent with a nanoparticles-dispersion liquid that nanoparticles are dispersed in a dispersion solvent, thereby concentrating and extracting the nanoparticles into a phase of the extraction solvent, and removing the dispersion solvent by filter-filtrating a liquid of concentrated extract, in which the extraction solvent is substantially incompatible with the dispersion solvent, and the extract solvent can form an interface after the extraction solvent is mixed with the dispersion solvent and left the mixture still; further a method of deaggregating aggregated nanoparticles, having the steps of: applying two or more ultrasonic waves different in frequency to a liquid containing aggregated nanoparticles, and thereby fining and dispersing the aggregated nanoparticles.

Method of concentrating nanoparticles and method of deaggregating aggregated nanoparticles

A light-emitting element having excellent light-emitting properties and with which it is possible to emit blue light at a high luminance for a long period of time, and an iridium complex for realizing the same. The light-emitting element has an external quantum efficiency of at least 5% and a light emission maximum wavelength &#x3bb; max of no more than 500 nm. Further, there is provided a light-emitting element including a light-emitting layer or a plurality of organic compound layers having the light-emitting layer, with at least one of the compound layers including at least one kind of a compound having a partial structure represented by the general formula K-0. In the general formula K-0, Rto Reach independently represents a hydrogen atom or a substituent, provided that if Ris a fluorine atom, Ris not a hydrogen atom.
