FLUORESCENT MATERIAL, METHODE FOR SYNTHESIZING FLUORESCENT MATERIAL AND LIGHT EMITTING DIODE COATED WITH FLUORESCENT MATERIAL

摘要

The present invention, strontium carbonate (SrCO ₃₎ and the flow path oxide europium (Eu ₂ O ₃₎ and is manufactured in a first step, the first step 1 of preparing a fluorescent mixture of orthosilicate group by mixing Methylsilsesquioxan (CH ₃ SiO _1.5) a second step of preparing a phosphor by the primary heat treatment made for 1 to 10 hours fluorescent mixture in an oxidizing condition at a temperature of 900 ~ 1500 ℃, first of 1100 ~ 1500 ℃ in reducing the primary heat-treating the phosphor in the step 2, conditions a third step of the second heat treatment consisting for 1 to 10 hours at a temperature, in the first step 5 to release the particles with entangled during step 4, the fluorescent substance pulverized by a fourth step of pulverizing the secondary heat-treated phosphor in step 3 is configured, can be produced round the phosphor particles can reduce the variation in the size of the phosphor particles and provides a phosphor synthesis method that can adjust the size of the phosphor particles.
