Description

実施例１−６：連続流プロセスによるＭｎ 4+ ドープＫ 2 ＳｉＦ 6 の調製
手順
反応容器として使用した２０００ｍｌの分液漏斗を約３００ＲＰＭの速度で撹拌した。３つの蠕動ポンプを使用して、すべての流量に対して厳密な制御を維持した。流量は、溶液Ａ及び溶液Ｂについては１５〜４０ｍＬ／分、溶液３については３０〜１００ｍＬ／分の間に設定した。実施例１〜６の溶液Ａ〜Ｃの間の原料の量及び配分を表２に示す。
比較例１及び２については、粒径及びスパンがより大きいスケールで増加したことが分かり、Ｄ10、Ｄ50及びＤ90は２１％〜２５％増加し、分布のスパンは１．２０から１．５４に増加した。対照的に、実施例１〜６の蛍光体では、スパンはバッチサンプルの場合よりも劇的に狭く、０．７４〜０．８７の範囲であり、Ｄ50は１５μｍ〜３１μｍの範囲であった。実施例３及び５については、蛍光体のＱＥは、プロセスにおいてより多量のＨＦを使用した実施例１、２及び４の蛍光体のＱＥと比較して低減された。実施例６〜８は、より高いドーパントレベルで狭い粒径分布を達成できることを実証している。
