| titleOfInvention | New manufacturing method of preparing spherical bam blue phosphor |
| abstract | The present invention relates to a new method for producing a spherical BAM blue phosphor, and more particularly, to a method for producing BaMgAl 10 O 17 : Eu 3+ used as a blue phosphor of a plasma display panel (PDP) or a lamp.n n n The present invention comprises (a) under glycol a group consisting of ⅰ) [(CH 3 ) 2 CHO] 3 Al, ii) BaCO 3 , (CH 3 CO 2 ) 2 Ba, and Ba (OH) 28 H 2 O. A mixture of barium compounds selected from iii) MgCO 3 or (CH 3 CO 2 ) 2 Mg 4 H 2 O, and iv) Eu 2 O 3 with a homogeneous molecular mixture of a fluorescent raw material and a melting agent Doing; (b) heat-treating the mixture in air at a temperature of 600 to 1000 ° C. to produce a mixed raw powder; And (c) heat treating the mixed raw material powder under a mixed gas atmosphere consisting of nitrogen and hydrogen in a closed reactor.n n n In the present invention, the fluorescent raw material can be uniformly mixed at the molecular level in the glycol solution to simplify the process and improve the yield, and a spherical blue phosphor having a uniform particle distribution of less than 5 μm of pure crystalline phase can be obtained. Implementation is possible. |
