Abstract: front page image
(EN)The purpose of the present invention is to provide a phosphor with high brightness. Furthermore, the purpose of the present invention is to provide a phosphor with negligible brightness reduction due to a reduction in particle diameters. A first phosphor is represented by the general formula, aYO3/2∙(3-a)CeO3/2∙bAlO3/2∙cGaO3/2∙fWO3 (where 2.80 ≤ a ≤ 2.99, 3.00 ≤ b ≤ 5.00, 0 ≤ c ≤ 2.00, and 0.003 ≤ f ≤ 0.020; however, 4.00 ≤ b + c ≤ 5.00). A second phosphor is represented by the general formula, aYO3/2∙(3-a)CeO3/2∙bAlO3/2∙cGaO3/2∙gK2WO4 (where 2.80 ≤ a ≤ 2.99, 3.00 ≤ b ≤ 5.00, 0 ≤ c ≤ 2.00, and 0.003 ≤ g ≤ 0.015; however, 4.00 ≤ b + c ≤ 5.00).
(FR)L'invention a pour objectif de fournir un luminophore de luminosité élevée. En outre, l'invention a pour objectif de fournir un luminophore dont la baisse de luminosité due à une réduction de diamètre de particule, est faible. Un premier luminophore est représenté par la formule générale aYO3/2・(3-a)CeO3/2・bAlO3/2・cGaO3/2・fWO3 (2,80≦a≦2,99; 3,00≦b≦5,00; 0≦c≦2,00; 0,003≦f≦0,020; mais 4,00≦b+c≦5,00). Un second luminophore est représenté par la formule générale aYO3/2・(3-a)CeO 3/2・bAlO3/2・cGaO3/2・gK2WO4 (2,80≦a≦2,99; 3,00≦b≦5,00; 0≦c≦2,00; 0,003≦g≦0,015; mais 4,00≦b+c≦5,00).
(JA) 輝度が高い蛍光体を提供することを目的とする。また、小粒子径化による輝度低下が少ない蛍光体を提供することを目的とする。第1の蛍光体は、一般式aYO3/2・(3-a)CeO3/2・bAlO3/2・cGaO3/2・fWO(2.80≦a≦2.99、3.00≦b≦5.00、0≦c≦2.00、0.003≦f≦0.020、ただし4.00≦b+c≦5.00)で表される。第2の蛍光体は、一般式aYO3/2・(3-a)CeO3/2・bAlO3/2・cGaO3/2・gKWO(2.80≦a≦2.99、3.00≦b≦5.00、0≦c≦2.00、0.003≦g≦0.015、ただし4.00≦b+c≦5.00)で表される。
