Title (EN) PHOSPHOR AND LIGHT EMITTING DEVICE
(FR) LUMINOPHORE ET DISPOSITIF ÉLECTROLUMINESCENT
(JA) 蛍光体及び発光装置
Abstract:
(EN) This phosphor contains Ce3+ as a luminescent center in a matrix garnet compound having a garnet structure. In the matrix garnet compound, some of the Ca atoms constituting the crystal of Lu2CaMg2(SiO4)3 are substituted with Mg atoms. This light emitting device has said phosphor. As a result, the present invention can provide: a novel garnet phosphor, which has improved temperature quenching and does not significantly shift the emission peak wavelength with respect to a Lu2CaMg2(SiO4)3:Ce3+ phosphor; and a light emitting device using the phosphor.
(FR) La présente invention concerne un luminophore qui contient du Ce3+ en tant que centre luminescent dans un composé de grenat matriciel ayant une structure de grenat. Dans le composé de grenat matriciel, certains des atomes de Ca constituant le cristal de Lu2CaMg2(SiO4)3 sont substitués par des atomes de Mg. Ce dispositif électroluminescent comprend ledit luminophore. En conséquence, la présente invention peut fournir : un nouveau luminophore de grenat, qui a une trempe à la température améliorée et ne décale pas significativement la longueur d'onde de pic d'émission par rapport à un luminophore Lu2CaMg2(SiO4)3:Ce3+ ; et un dispositif électroluminescent utilisant le luminophore.
(JA) 蛍光体は、ガーネット構造を有する母体ガーネット化合物中に、発光中心であるCe3+が含まれてなる蛍光体である。そして、母体ガーネット化合物は、LuCaMg(SiOの結晶を構成するCaの一部がMgで置換されている。また、発光装置は、上述の蛍光体を備える。これにより、LuCaMg(SiO:Ce3+蛍光体に対して発光ピーク波長を大きくシフトさせることなく、温度消光が改善された、新規なガーネット蛍光体及びこれを用いた発光装置を提供することができる。
