Abstract: A light source device includes: an excitation light source that emits excitation light having an energy density of 10 W/mm2 or more; and a phosphor layer that has phosphor particles embedded in the matrix. The phosphor particles include at least one selected from the group consisting of metal oxides represented by a following formula (1) and metal oxides represented by a following formula (2). Y3-x1-y1R1y1Cex1Al5-z1Gaz1O12  (1) Y3-x2-y2R2y2Cex2Al5-z2Scz2O12  (2) In the formula (1), R1 includes at least one selected from the group consisting of Gd and Tb, and x1, y1, and z1 satisfy 0.003≤x1≤0.03, 0≤y1≤2.1, and 0≤z1≤2.2, respectively. In the formula (2), R2 includes at least one selected from the group consisting of Gd and Tb, and x2, y2, and z2 satisfy 0.003≤x2≤0.03, 0≤y2≤2.1 and 0≤z2≤1.5, respectively.

Abstract: A wavelength conversion device of the present disclosure includes a substrate, a phosphor layer that has a matrix containing zinc oxide and phosphor particles embedded in the matrix and that is supported by the substrate, a dielectric layer disposed between the substrate and the phosphor layer, and a protective layer that is disposed between the phosphor layer and the dielectric layer and that has an isoelectric point equal to or larger than 7. A main surface of the substrate includes, for example, first and second regions. The phosphor layer covers, for example, only the first region out of the first and second regions.

Abstract: A wavelength conversion member includes a substrate, a dichroic mirror layer, an SiO2 layer, a ZnO layer, and a phosphor layer, which are sequentially stacked from the substrate. The dichroic mirror layer reflects at least part of light incident from the above. The phosphor layer includes a plurality of phosphors and ZnO between the phosphors.
