Ca 7−y Eu y Si 10 O 6 N 14 (1)
(式中、yは0.013≦y≦0.015を満たす。)で表され、格子定数a(nm)が1.5<a<1.6を満たす立方晶系で空間群Pa−3(No.205)の結晶構造を有することを特徴とする蛍光体を提供する。
AxLySizObNc (1)
(式中、Aは少なくともCaを含み、Ba、Sr、Mg又はZnのいずれか1種又は2種以上を含んでいてもよい元素を示し、Lは少なくともEuを含み、Ce、Pr、Yb、Tm、Tb又はSmのいずれか1種又は2種以上を含んでいてもよい元素を示し、xは5.8≦x≦7.8、yは0.001<y≦0.2、zは6≦z≦10、bは6≦b≦8、cは9≦c≦14を満たす数値を示す。)で表され、格子定数a(nm)が1.45<a<1.65を満たす立方晶系の結晶構造を有することを特徴とする。
A7-yLySi10O6N14 (2)
(式中、A、L、yはそれぞれ式(1)中に示すA、L、yと同じものを示す。)で表され、格子定数a(nm)が1.5<a<1.6を満たす立方晶系で空間群Pa−3(No.205)の結晶構造を有する蛍光体が特に好ましい。式(2)で表される蛍光体は上記組成により、格子定数a(nm)が1.5<a<1.6の立方晶系で空間群Pa−3(No.205)の結晶構造を有する。このような立方晶系を有することにより、青色光により励起され、青緑色の蛍光を効率よく発光し、結晶性に優れた蛍光体が得られ、かかる蛍光体においては、励起光による結晶格子欠損に起因するフォノンの生成を抑制し、蛍光の発光が阻害されるのを抑制させ得る。
[実施例1]
粉末原料として、CaCO3を3.08g、Si3N4を1.92g、Eu2O3を0.01g秤量し、原料を混合した。混合物を窒化ホウ素ルツボに充填し、電気炉にセットし、0.9気圧の窒素還元雰囲気中において1500℃で3時間焼成した。焼成後は徐冷して、得られた焼成物を粉砕混合、洗浄して、目的のCa7-yEuySi10O6N14(y=0.015)の蛍光体を得た。
得られた蛍光体について、蛍光分光光度計(RF−5300PC:島津製作所製)により、大気中室温雰囲気下で、励起波長を変化させ、蛍光体の発光ピーク波長をモニターして測定を行った。蛍光体を励起可能な波長範囲は330nm近傍にピークを有し、300〜500nmに及んだ。励起光波長に対するPLE強度(励起スペクトル)を図5中の点線で示す。
得られた蛍光体について、励起光として365nmを用いて、蛍光分光光度計(RF−5300PC:島津製作所製)により、大気中室温雰囲気下で行った。発光は490nm近傍にピークを有し、450〜600nmに及んだ。得られた蛍光体のPL強度(発光スペクトル)を図5中の実線で示す。
粉末原料として、CaCO3を3.16g、Si3N4を1.73g、Eu2O3を0.01g、SiO2を0.11g秤量して用いた他は、実施例1と同様にして蛍光体を作製し、目的のCa7-yEuySi10O6N14(y=0.013)の蛍光体を得た。得られた蛍光体について、PLE測定、PL測定を行った。PLE強度を点線で、PL強度を実線で、図6に示す。
