Title:
Eu-CONTAINING INORGANIC COMPOUND, LUMINESCENT COMPOSITION CONTAINING THE SAME AND ILLUMINANT, SOLID-STATE LASER APPARATUS AND LIGHT EMITTING DEVICE
Document Type and Number:
Japanese Patent JP2007254723
Kind Code:
A
Abstract:
To optimize an amount of Eu dope in a garnet type Eu-containing inorganic compound having a polycrystalline structure by elucidating relation between the amount of the Eu dope and light emission characteristics.
The Eu-containing inorganic compound has the polycrystalline structure in which Eu is doped and treated to be a solid solution to the parent garnet type compound and contains >0.5 mole% to ≤50.0 mole% amount of the Eu dope occupying octadentate sites of the garnet structure. The amount of the Eu dope occupying the sites of the octadentate garnet structure is preferably 5.0-30.0 mole%.
