Description
(実施例1)
無機ナノ蛍光体粒子として、CdSe(コア)/ZnS(シェル)のコアシェル構造を有し、粒径が3nm(緑色)と6nm(赤色)のものを用いた。トルエンに無機ナノ蛍光体粒子が3μMとなる様に調整し、テトラエトキシシランを0.02μMとなる様に添加し20時間攪拌を行った。続けて、トルエン10mlにエーロゾルOTを1.5gを添加、混合した後、上記の無機ナノ蛍光体粒子の溶液を0.3ml加え、さらに6.25質量%のアンモニア水溶液を0.3ml加え、テトラエトキシシランを20μl加えて20時間攪拌した。その後、50℃の温度で乾燥し、保護膜付着蛍光体粒子を作製した。得られた保護膜付着蛍光体粒子においては、約1個〜5個の無機ナノ蛍光体粒子からなる凝集体が無機保護膜で被覆されていた。凝集体の平均粒子径は、200nmであった。また、無機ナノ蛍光体粒子の1体積部に対し、無機保護膜が約4.5×103〜1.3×105体積部付着していた。
焼成温度を500℃とする以外は、実施例1と同様にして、波長変換部材を製造した。
保護膜付着蛍光体粒子を作製せずに、無機ナノ蛍光体粒子のまま、分散媒としてのトルエン中に20質量%含まれるように分散させて分散液を調製し、この分散液を、実施例1と同様にして圧粉体に混入させて予備成形体を作製した。この予備成形体を、実施例1と同様にして焼成し、波長変換部材を製造した。
実施例1では、得られた波長変換部材の色が、無機ナノ蛍光体粒子と同じ色をしているのに対して、比較例1の波長変換部材は、無機ナノ蛍光体粒子の色が焼成により消滅した。比較例2の波長変換部材は、無機ナノ蛍光体粒子と同じ色をしていた。
実施例1で用いたガラス粉末と同じガラス組成を有するガラス板の上に、実施例1で調製したゾル溶液を塗布し、厚さ20nmの無機保護膜を形成した。無機保護膜を形成したガラス板を、実施例1と同じ150℃の温度で焼成した。焼成後、ガラス板の上に無機保護膜が無機保護層として残存していることを確認した。
