複合積層体サンプルの調製
ポリ(メチルメタクリレート)、すなわちPMMA(Aldrich社製)(GPCによる分子量120000)をK2SiF6:Mn4+(PFS)及びYAGと別々に混合することによって2種類のサンプルを調製した。300μmのふるいに掛けた4.5gのPMMAを2.5gのK2SiF6:Mn(5mol%Mn、粒径20μm)と混合し、混合物を再度ふるい(300μm)に掛けてサンプル混合物1を調製した。また、150μmのふるいに掛けた4.9gのPMMAを0.59gのYAG(Aldrich)と混合し、混合物を再度ふるい(150μm)に掛けてサンプル混合物2を調製した。この2種類のサンプル混合物を真空チャンバ内で約15分にわたって個別に脱気した。直径7.5cm、厚さ400μmの円盤形鋳型にサンプル混合物1を注入し、直径7.5cm、厚さ200μmの円盤形鋳型にサンプル混合物2を注入した。次に、混合物が入った各鋳型を真空中かつ200℃で80psiの圧力でプレスした後、175℃で550psiの圧力でフレームプレスを行った。この2つのプレス工程では、温度が70℃未満に下がってから加圧を解除した。PFSを含有するサンプルテープ1は約410μm厚であり、YAGを含有するサンプルテープ2は約205μm厚であった。この2本の円形テープを上下に重ねて積層し、その積層体の上下に離型フィルムを配置した。この積層体を真空ラミネート機に入れて180℃に加熱した後、80psiの圧力でプレスして2本のテープを結合した。次に、積層体を加圧下で冷却した。得られた複合積層体は約615μm厚であり、YAG又はPFS蛍光体の明確な領域が存在した。
複合積層体(上で調製したもの)を青色LEDチップ(ピーク発光波長:450nm)上にそれぞれ配置することによって2種類のサンプル(サンプル1とサンプル2)を調製した。シリコーン層を補助的に使用し、この複合積層体をLEDチップに接着した。サンプル1は、PFS含有側がLEDチップ上になる(PFSが下側)ように複合積層体をLEDチップ上に配置し、サンプル2は、複合積層体のYAG含有面をLEDチップ上に配置した(YAGが下側)。図4はサンプル1とサンプル2の放射スペクトルを、表1はそのスペクトル特性を示す。
