摘要:
It is an object to provide a light-emitting material with higher emission luminance than conventional one in terms of a crystalline structure of the light-emitting material, as a light-emitting material using an inorganic compound. First baking is performed after mixing gallium arsenide, gallium phosphide, or gallium antimonide with manganese to form a first baked product, second baking is performed after mixing a base material with an element for forming a luminescent center material or a compound including the element to form a second baked product, and third baking is performed after mixing the first baked product with the second baked product, so that a light-emitting material is manufactured.
摘要:
Inorganic phosphor-containing polymer particles that include an inorganic phosphor and a transparent material. The transparent material is preferably a vinyl resin that is a polymer of a vinyl compound. It is preferable that the vinyl compound includes 10% by mass or more of a vinyl compound having a viscosity (at 25°C) of from 5 mPa.s to 30 mPa.s, or includes at least one of a compound having a structure represented by the following Formula (I-1) or the following Formula (I-2). In Formulae (I-1) and (I-2), each of R 1 and R 2 independently represents a hydrogen atom or an alkyl group. R 1 and R 2 may be linked to each other to form a ring. The inorganic phosphor is preferably surface-modified with a surface treatment agent, more preferably surface-modified with a coupling agent, still more preferably surface-modified with a silicone oligomer having a reactive substituent.
