この実施例は、Mg1−xCoxWO4(x=0.1、0.2、0.3、0.4、及び0.5)の調製に関する。MgO(純度99%)、WO3(純度99.995%)、及びCoO(99.99%)を化学量論比でめのう乳鉢中において乳棒により完全に混合した。混合物を空気中で1100℃で12時間か焼した。得られた粉末を、Philips X’pert Pro回折計を用いて、NiフィルターしたCuKα1放射線を使用して、X線粉末回折(XRD)により調べた。MgWO4は、鉄マンガン重石と同形の単斜構造で結晶化し、空間群がP2Icであり、C2h点群対称性を有する。構造は、ジグザグ鎖を形成する縁を共有するMgO6及びWO6八面体単位の交互層からなる。図1は、コバルトドープMgWO4のXRDパターンを示している。回折ピークはすべて、JCPDSファイル番号(01−073−0562)と一致するP2/c空間群を有する単斜構造にインデックス付けすることができる。形態学的解析は、JEOL社のJSM−5600LV SEMを用いて走査型電子顕微鏡により行った。顔料の粒径は、1〜2.5amの範囲で変化する。粉末の光反射率は、参照を図2に示すように、PTFEを使用してUV−Vis分光光度計(Shimadzu社、UV−2450)で測定した。色度座標は、CIE−LAB1976カラースケールから決定した。値a*(赤−緑軸)及びb*(黄−青軸)は、色彩を示す。値L*は、中間灰色に関連するような色の明るさ又は暗さを表す(Table 1(表1))。コバルト支持顔料の着色性能は、Co2+イオンの配位に非常に依存している。Mg1−xCoxWO4粉末の青色の由来を理解するために、我々はUV−可視NIRスペクトルを測定する。得られたスペクトルは、それぞれ1500nm、730nm、及び580nmに現われる3つのスピン許容遷移4T1g(4F)−4T2g(v1)、4T1g(4F)−4A2g(v2)、4T1g(4F)−T1g(4P)(v3)に起因する3つのバンドを主として含む。これらはCoO6発色団の3つのスピン許容遷移である。
L*=46.28、a*=6.33、b*=−46.97(x=0.2)、及びL*=42.54、a*=4.46、b*=−43.2(x=0.3)
Mg1−xCoxNb2O6青色顔料の調製
この実施例は、Mg1−xCoxNb2O6(x=0.1、0.2、0.3、0.4、及び0.5)の調製に関する。MgO(純度99%)、Nb2O5(純度99.995%)、及びCoO(99.99%)を化学量論比でめのう乳鉢中において乳棒により完全に混合した。混合物を空気中で1300℃で6時間か焼した。得られた粉末を、Philips X’pert Pro回折計を用いて、NiフィルターしたCuKα1放射線を使用して、X線粉末回折(XRD)により調べた。AB2O6構造に関連するほとんどの酸化ニオブは、空間群がpbcnであるコロンバイト構造を有する。図5に示した化合物のXRDパターンは、粉末X線回折ファイル(01−088−0708)に十分一致している。コバルトドープMgNb2O6は、pbcn空間群を有する斜方晶構造で結晶化する。形態学的解析は、JEOL社のJSM−5600LV SEMを用いて走査型電子顕微鏡により行った。顔料の粒径は、1.5〜2.5μmの範囲で変化する。粉末の光反射率は、参照を図6に示すように、PTFEを使用してUV−Vis分光光度計(Shimadzu社、UV−2450)で測定した。色度座標は、CIE−LAB1976カラースケールから決定した。値a*(赤−緑軸)及びb*(黄−青軸)は、色彩を示す。値L*は、中間灰色に関連するような色の明るさ又は暗さを表す(Table 1(表1))。Mg1−xCoxNb2O6の光吸収スペクトルは、3つのスピン許容遷移に起因する3つのバンドを主として含む。4T1g(4F)−4T2g(v1)、4T1g(4F)−4A2g(v2)、4T1g(4F)−T1g(4P)(v3)。近IR領域の約1500nmにある単一の非常に広いバンドは、v1遷移に起因する。730nm、580nmのバンドは、v2及びv3遷移に起因する。
L*=52.78、a*=−0.97、b*=−36.16(x=0.5)
Mg1−xCoxTiO3青色顔料の調製
この実施例は、Mg1−xCoxTiO3(x=0.1、0.2、0.3、0.4、及び0.5)の調製に関する。MgO(純度99%)、TiO2(純度99.995%)、及びCoO(99.99%)を化学量論比でめのう乳鉢中において乳棒により完全に混合した。混合物を空気中で1200℃で6時間か焼した。得られた粉末を、Philips X’pert Pro回折計を用いて、NiフィルターしたCuKα1放射線を使用して、X線粉末回折(XRD)により調べた。ゲーキーライト(MgTiO3)は、菱面体晶空間群R−3及び単位格子当たり6個の式単位を有するイルメナイト構造型(ATiO3、A=Mg、Mn、Fe、Zn)に属する。図9は、コバルトドープMgTiO3のXRDパターンを示す。反射はすべて、粉末回折ファイル01−079−0831に従って完全にインデックス付けすることができる。MgTiO3の構造は、MgO6八面体及びTiO6八面体からなる。形態学的解析は、JEOL社のJSM−5600LV SEMを用いて走査型電子顕微鏡により行った。顔料の粒径は、2〜4μmの範囲で変化する。粉末の光反射率は、参照を図10に示すように、PTFEを使用してUV−Vis分光光度計(Shimadzu社、UV−2450)で測定した。色度座標は、CIE−LAB1976カラースケールから決定した。値a*(赤−緑軸)及びb*(黄−青軸)は、色彩を示す。値L*は、中間灰色に関連するような色の明るさ又は暗さを表す(Table 1(表1))。Mg1−xCoxTiO3粉末の青色は、Xが非常に低い値でも明らかである。Co2+ドープMgTiO3のUV−可視NIRスペクトルは、青色がCo(II)の八面体組込み(octahedral incorporation)に起因することを示している。得られたスペクトルは、それぞれ1500nm、730nm、及び580nmに現われる3つのスピン許容遷移4T1g(4F)−4T2g(v1)、4T1g(4F)−4A2g(v2)、4T1g(4F)−T1g(4P)(v3)に起因する3つのバンドを主として含む。
L*=54.13、a*=−11.04、b*=−25.61(x=0.1)。
