Description
Sr1−xCaxGa2S4:yEu2+・zGa2S3(I)
式中、xは0.0001〜1であり、yは発光放出を提供するために十分なEu2+を定義する値(または例えばSr1−xCaxGa2S4:yEu2+のモル量に基づいて0.001〜0.1)であり、zはSr1−xCaxGa2S4のモル量に基づいて0.0001〜0.2である。
1)相同定は、存在する相を判定するために、実験データを粉末回折ファイル[Powder Diffraction File,International Centre for Diffraction Data,スワスモア、ペンシルベニア州、米国、毎年刊行]と比較することによって実施した。
2)相が同定されたら、構造情報をICSDデータベースから得た。
3)リートベルトリファインメントは、Materials Data Inc.(リバモア、カリフォルニア州、米国)が製造したJade software v.6.5ソフトウェアパッケージを使用して、実行された。リファインされた構造パラメータは、重量分率、格子パラメータ、およびラインプロフィールシェイプファンクション、機器の系統的誤差、および等方性熱パラメータであった。他の構造パラメータ、例えば原子配置およびサイト占有率は、サンプルが混合物を含有する場合には、これらのパラメータをリファインすべきでないことが、経験により示されたため、リファインされなかった。
Sr(NO3)2+Ca(NO3)2+Eu(NO3)2+(NH4)2CO3→SrxCa1−xCO3↓+Eu(OH)3↓+NH4OH
同時沈殿した炭酸塩は、炭酸塩をその硫酸塩に変換するために、過剰の硫酸アンモニウム(例えば25%モル過剰)を用いて、例えば約200℃にて焼成し、続いて例えば約1100℃のより高温で、焼成することができる。ガリウム塩、例えば硝酸塩の酸性溶液を硫酸塩の溶液に添加できる。pHを中性またはさらに塩基性にして(例えば水酸化アンモニウムを使用して)、粒子を沈殿させることができる。得られた粉末を乾燥、粉砕して、(例えばアルミナ製の)耐火ボートに入れ、硫化水素中で例えば5時間に渡って管状炉内で約800℃にて焼成できる。得られた生成物は式:
Sr1−xCaxGa2S4:yEu2+・zGa2S3 (Ic)
を有し、式中、zは、例えば、0.0001〜0.1(または0.01〜10モルパーセント)である。均一性を高めるために、生成物は、例えば粉砕して粉末として、硫化水素中で約900℃にて約2時間に渡って再焼成してもよい。
Ga(NO3)3+Eu(NO3)3+NH4OH→Ga(OH)3/Eu(OH)3↓(ゲル状)(1)
CaSO4+Ga(OH)3/Eu(OH)3+H2S→CaGa2S4:Eu・xGa2S3 (3)
Claims (8)
- 2価ユウロピウムによってドーピングされ、式中、xは0.0001〜1であり、yは発光放出を提供するために十分なEu2+を定義する値であり、zはSr1−xCaxGa2S4:yEu2+のモル量に基づいて0.0001〜0.2である以下の式:
