| titleOfInvention | A kind of near ultraviolet excitated phosphoric acid salt white fluorescent powder and preparation method thereof |
| abstract | The invention discloses a kind of near ultraviolet excitated phosphoric acid salt white fluorescent powder and preparation method thereof, combination matching general formula is Lan 0.98-x pOn 4 : Cen 3+ 0.01 , Lin + 0.03 , Eun 3+ x , x is Eun 3+ molecular fraction in this compound, wherein 0 < x≤0.1.Its preparation method is by compound Homogeneous phase mixing corresponding to La, Ce, Li, Eu, then adds phosphoric acid salt, grinds after mixing, and insulation obtains presoma; Presoma described in roasting obtains near ultraviolet excitated phosphoric acid salt white fluorescent powder.The commercial near-ultraviolet ray that phosphoric acid salt white fluorescent powder of the present invention can be 370 ~ 410nm by wavelength excites; have good market outlook, and the productive rate that the method obtains is more than 99%, roasting process does not need the protection of reducing atmosphere; easy to control, technique is simple. |
