Abstract
【解決手段】原材料液に対して400nm未満の波長の高エネルギー光を照射して、粒径200nm以下のナノ粒子を製造する。製造するナノ粒子がPtナノ粒子の場合には、塩化白金(IV)酸六水和物(H2Pt(IV)Cl6・6H2O)をエタノール(C2H5OH)中に溶解したものが原材料液として用いられる。
【選択図】図1
Description
本発明によれば、回収効率に優れ、良質の無機ナノ粒子コロイド溶液や任意の組成の多元合金あるいは多元化合物のナノ粒子を容易に製造することができる。
原材料液に対して400nm未満の波長の高エネルギー光を照射することにより、粒径200nm以下のナノ粒子を製造することができる。
高エネルギー光の照射経路が一定の場合、収率を高めるため、照射する原材料液を攪拌することが好ましい。
原材料液に照射した高エネルギー光は、原材料液をそのまま透過させても、反射させて繰返し透過させてもよい。
表1と表2に、用いたPtおよびFeナノ粒子合成用の前駆体溶液の調整表を示す。表1がPtナノ粒子生成用前駆体溶液、表2がFeナノ粒子生成用前駆体溶液である。
製造するナノ粒子がPtナノ粒子の場合には、塩化白金(IV)酸六水和物(H2Pt(IV)Cl6・6H2O)をエタノール(C2H5OH)中に溶解したものを原材料液として用いた。また、分散剤として水溶性ポリマーのPVP ((C6H9NO)n)を添加したものと添加しないものを用意した。
照射する高エネルギー光としては、KrFエキシマレーザー光を用いた。その照射条件を表3にまとめて示す。
