Method for fabricating of YAG : Ce phosphor powder by polymer solution route and alumina seed application

摘要

the present invention is a PVA solution using the synthesis of YAG: Ce ^{3 +} relates to a method for manufacturing a phosphor powder, and more particularly, Y and PVA valence contrast of the cation of the metal to the Ce salt mixture 2: 1 to 20: 1 (valence of a metal cation: atoms of the PVA anion) and the ratio of addition of the PVA solution to this, Al _{in the mixed aqueous solution of 2} O ₃ seed (seed) calcining a precursor of the addition of the powder thus obtained gel-like and heat-treatment (sintering) of YAG by the synthesis method using the PVA solution, characterized in that:. Ce ^{3 +} relates to a method for producing a phosphor powder According to the invention, the low heat treatment temperature and the short retention time, and milling step, and then drying process without dispersing agent has a light emission intensity of the YAG fluorescent material and the existing class level, it is possible the synthesis of the phosphor particles forming controllable. ;
