Suppression or enhancement of various properties of a liquid fluid is aimed by improving uniform dispersion of nanoparticles by means of making a state in which no oxidized film exists on the surfaces of the nanoparticles to be dispersed in the liquid fluid. The location of the liquid fluid is confirmed with ease by enhancing the brightness of light emission of the fluid through uniform dispersion of the nanoparticles in the liquid fluid containing a material having a flame reaction. In this way, as to liquid fluids utilized in various industries, it is possible to offer a technology to desirably enhance or suppress a property desired to be enhanced and a property desired to be suppressed among various properties that its constituents have.

Nanoparticle-dispersed high-performance liquid fluid, production method and apparatus for the fluid, and leak detection method for the fluid

A light-emitting material is provided allowing a light-emitting body having an excellent low-excitation characteristic and high brightness to be obtained by using a light-emitting material containing a light-emitting base material that emits light through radiative transition of electrons in material atoms, the light-emitting base having nanoparticles added thereto and dispersed therein, the light-emitting material also allowing a reduction in excitation energy and an increase in brightness to be simultaneously achieve, thereby allowing, for a wide range of light-emitting bodies, a reduction in excitation energy and a significant improvement in brightness to be achieved in a simple structure. Also provided is a light-emitting body having the light-emitting material and a light-emitting method.
