Summary:The present invention relates to a thorium-doped garnet-based phosphor and to a light-emitting device using same. Specifically, the present invention uses thorium as an active agent and thus provides a garnet-based phosphor having optical properties and thermal stability which is superior to that of a typical garnet phosphor using a cerium active agent, and provides a light-emitting device using the garnet-based phosphor as a light source. La présente invention concerne un luminophore à base de grenat dopé au thorium et un dispositif photoémetteur l'employant. Spécifiquement, la présente invention emploie du thorium comme agent actif et concerne donc un luminophore à base de grenat présentant des propriétés optiques et une stabilité thermique qui sont supérieures à celles d'un luminophore de grenat classique employant un agent actif de cérium et elle concerne un dispositif photoémetteur employant le luminophore à base de grenat comme source lumineuse.
