    Abstract: A light-emitting device includes a package having a recessed portion defined by a bottom surface and lateral walls surrounding the bottom surface, first and second light-emitting elements aligned in the longitudinal direction on the bottom surface, and a wavelength conversion member in the recessed portion, the wavelength conversion member converting light from the first light-emitting element. The first and second light-emitting elements each have a polygonal shape other than a rectangular shape in a front view. The first and second light-emitting elements are disposed away from each other so that a longest side of each light-emitting element will be substantially parallel to the longitudinal direction of the bottom surface and so that sides facing each other will be substantially parallel to each other. The wavelength conversion member is disposed at least in a region on the bottom surface between the first and second light-emitting elements.

    Abstract: A wavelength conversion member containing a fluorescent material having, for example, a perovskite-type structure maintained with high light emission intensity; a light emitting device; and a method for producing a wavelength conversion member. The wavelength conversion member includes a translucent member containing a resin, a wavelength conversion layer containing a fluorescent material having, for example, a perovskite-type structure, and a composition of ABX3, and a first intermediate layer between the translucent member and the wavelength conversion layer. The method for producing a wavelength conversion member includes forming a first intermediate layer on a surface of a first translucent member containing a resin, and forming a first wavelength conversion layer containing a first fluorescent material having, for example, a perovskite-type structure on a surface of the first intermediate layer.
