Abstract

　組成が下記化学式（１） 　　Ｌｎ３αｘＡｌ５－ｘ－ｙβｙＯ１２：Ｃｅ　……（１） 　（但し、ＬｎはＹ，Ｌｕ，Ｇｄから選択される少なくとも1種の元素であり、α及びβは対をなす元素であり、その組合せ（α，β）は（Ｍｇ，Ｓｉ），（Ｂ，Ｓｃ）および（Ｂ，Ｉｎ）のいずれかであり、ｘ，ｙはそれぞれ原子比でｘ＜２，ｙ＜２，０．９≦ｘ／ｙ≦１．１なる関係式を満たす係数である。）で表されることを特徴とする蛍光体である。この蛍光体と、発光ピーク波長が４３０～４７０ｎｍである青色発光ダイオードとを組合せてＬＥＤランプが形成される。上記蛍光体によれば、赤色発光成分を効果的に補うことができる蛍光体が提供される。また、上記蛍光体をＬＥＤランプの蛍光体として使用することにより、演色性が優れた発光を放出できるＬＥＤランプが提供される。
