Abstract
Description
(1)500mlの三角フラスコに測定対象の蛍光体0.2gを秤量した。
(2)イオン交換水50mlを(1)に加え、スターラーにて撹拌した。
(3)撹拌をしたままビュレットよりメタノールを滴下させ、蛍光体の全量がイオン交換水に懸濁された時の滴下量を測定した。
(4)次式より疎水化度を求めた。
疎水化度(%)=(メタノール滴下量(ml))×100/(メタノール滴下量(ml)+イオン交換水量(ml))
本発明に係る蛍光体は、従来の蛍光体にコーティング層を積層させたものである。そのため、従来の蛍光体を比較例1とする。比較例1の蛍光体について説明する。
常温下で、容量500mlのテフロン(登録商標)製のビーカーに濃度55質量%フッ化水素酸(ステラケミファ株式会社製)100mlを入れ、K2SiF6粉末(森田化学株式会社製)3g、及び次の製造工程で製造した粉末状のK2MnF6の0.5gを溶解させ、溶液を調製した。
K2MnF6の製造工程は、非特許文献1に記載されている製造工程を採用した。具体的には次のとおりである。
溶液調整工程後の溶液に、水150mlを入れた後、10分撹拌した。攪拌後、静置して固形分を沈殿させた。この固形分が蛍光体である。該溶液に水を加えることで、前記式のフッ化物蛍光体の飽和濃度が変化し、これにより蛍光体が析出する。
析出工程後の溶液の上澄み液を除去した後、20質量%のフッ化水素酸で洗浄を行い、さらにメタノールでの洗浄を行った。メタノールでの洗浄は、フッ化水素酸の残存分の除去を目的としたものである。
分級工程は、蛍光体の粒度のばらつきを抑制し、一定範囲内に調整するものであり、具体的には、所定の大きさの開口部のある篩を通過したもの、しなかったものに分ける工程である。目開き75μmのナイロン製篩を用い、この篩を通過したものだけを分級し、最終的にK2SiF6:Mnの蛍光体1.3gを得た。この蛍光体を比較例1とする。
膜厚(μm)=(コーティング層の体積(m3)/蛍光体の表面積(m2))×106
コーティング層の体積(m3)=コーティング層の質量(g)/(コーティング層の密度(g/cm3)×106)
蛍光体の表面積(m2)=蛍光体の比表面積(m2/g)×蛍光体全体の質量(g)
内部量子効率及び外部量子効率は、分光光度計(大塚電子株式会社製MCPD−7000)を用いて測定した。励起光として波長455nmの青色光を用いた。
内部量子効率(=Qem/(Qex−Qref)×100)
外部量子効率(=Qem/Qex×100)
分光光度計(大塚電子株式会社製MCPD−7000)を用いて測定した。励起光として波長455nmの青色光を用いた。
外部量子効率の測定は分光光度計(大塚電子株式会社製MCPD−7000)を用いた。
実施例2乃至8の蛍光体は、実施例1の蛍光体のコーティング層を、表1に記載の素材、膜厚に変更した以外、実施例1と同様に製造した蛍光体である。
Claims (4)
