    摘要： According to one embodiment, the luminescent material emits light with an emission peak within a wavelength range of 490 to 580 nm when excited with light having a wavelength range of 250 to 500 nm and includes a particle containing a Sr3Si13Al3O2N21-based crystal activated by Eu. The particle includes an outer region which is within a depth of 5 nm from a surface of the particle and an inner region which is deeper than the outer region. The outer region and the inner region satisfy a ratio Oouter/Oinner of 1.0 to 3.8. Oouter is an average of oxygen concentration in the outer region and Oinner is an average of oxygen concentration in the inner region.

    摘要： Disclosed is a white light emitting device including a semiconductor light emitting element configured to emit near ultraviolet light having a peak wavelength ranging from 380 to 410 nm, a first phosphor layer and a second phosphor layer. The first phosphor layer contains a blue-emitting phosphor configured to emit blue light by the near ultraviolet light, and a red-emitting phosphor activated by trivalent europium and configured to emit red light by the near ultraviolet light. The second phosphor layer contains a green-emitting phosphor configured to emit green light by the near ultraviolet light. The semiconductor light emitting element, the first phosphor layer and the second phosphor layer are laminated in this order to emit white light.
