Abstract:
PURPOSE: A luminous body and a manufacturing method thereof are provided to obtain a light property irradiating the light of an infrared ray, and to secure the stability of the luminous body. CONSTITUTION: A manufacturing method of a luminous body comprises the following steps: mixing a first solution including water and lanthanide metal salt selected from the group consisting of calcium salt, magnesium salt and zinc salt as a host, and a second solution including the water and molybdate salt; separating the mixture by reacting the mixture obtained from the previous step; producing luminous powder by heating the mixture at 900~1,000 deg C, and pulverizing the powder with a pulverizing device.
