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 europium oxide ( Eu ₂ O ₃ ) and Methylsilsesquioxan (CH ₃ SiO _1.5 ) mixed with a mixture of fluorescent orthosilicate group a first step, the second step for producing a fluorescent substance composed by the primary heat-treated for 900 ~ 1500 for 1 to 10 hours at a temperature in the oxidizing conditions fluorescence mixture prepared in the first step of producing, in a second step 1 a third step of the second heat treatment consisting of 1-10 hours at a temperature of 1100 ~ 1500 in the heat-treated phosphor difference reducing conditions, the fourth step of pulverizing the secondary heat-treated phosphor in the third step, a fourth step in the grinding The phosphor is composed of a fifth step to release entangled particles, the phosphor particles can be produced the phosphor particles may be rounded to reduce the size of the deviation, and provides a phosphor synthesis method that can adjust the size of the phosphor particles.
