Abstract
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.
