    摘要： A production method capable of producing ITO particles without using a solvent with a high boiling point as a solvent used in the producing step by a simple treatment method without through a heating process in an atmosphere which disadvantageously causes sintering among the ITO particles to coarsen the ITO particles. An ITO powder suitable for a coating material for a transparent electroconductive material, being produced by a first step of dissolving salt containing indium and salt containing tin into an organic solvent, then adding to this organic solvent, an organic solvent containing a basic precipitant, to thereby manufacture a mixture of a precursor containing indium and tin, and the organic solvent; and a second step of applying heat treatment to the mixture of the precursor containing indium and tin, and the organic solvent in a pressurizing vessel at 200° C. or more and 300° C. or less, to generate ITO particles.

    摘要： A phosphor having an excitation band relative to lights in the wide range of wavelengths from ultraviolet to visible light, and having an emission spectrum in the red range and so on, with a wide half value width, and an LED and a light source using the phosphor and emitting white and other color lights with good color rendering properties are provided. Powdered raw materials of Ca3N2 (2N), CaO (2N), AlN (3N), Si3N4 (3N), and Eu2O3 (3N) are prepared, and the respective raw materials are mixed to have a mole ratio of the respective elements of Ca:Al:Si:Eu=0.985:1:1:0.015. The mixed raw materials are fired at 1000° C. or higher in an inert atmosphere for three hours, and thereafter pulverized to obtain a phosphor having a composition of CaAlSiN2.83O0.25:Eu, which is one example of the phosphor satisfying the above described object. Furthermore, by combining the phosphor with an appropriate LED or a light source emitting from ultraviolet light to visible light, the LED and the light source emitting white and other color lights with good color rendering properties can be obtained.
