Wavelength conversion member and white light emitting device using same |
| abstract |
A wavelength conversion member converts a wavelength of laser light. The wavelength conversion member includes a substrate having reflectivity with respect to the laser light, and a phosphor layer including a phosphor for converting the laser light into light having a longer wavelength than that of the laser light, the phosphor layer being on the substrate. The phosphor layer includes a plurality of concave parts, each having a depth of 50% or more and 80% or less with respect to a film thickness of the phosphor layer and an opening width of 50 μm or more, on a surface of the phosphor layer, the surface irradiated with the laser light. A distance between adjacent concave parts of the plurality of concave parts is smaller than a spot diameter of the laser light to be emitted to the surface of the phosphor layer. |
