摘要： A phosphor contains: a crystal represented by MGa2S4, where M includes at least one element selected from the group consisting of Ba, Sr, and Ca; and an element A that functions as a luminescent center, wherein diffraction peaks are observed in a range of 2θ=27.6° or more and 28.3° or less and a range of 2θ=28.45° or more and 28.75° or less in an X-ray diffraction pattern obtained through measurement that uses CuKα rays performed using an X-ray diffractometer. A method for producing a phosphor includes sintering an ingredient composition that contains a gallium element (Ga), a sulfur element (S), an element M, where the element M includes at least one selected from the group consisting of Ba, Sr, and Ca and an element A that functions as a luminescent center while a portion of the ingredient composition is melted. A light emitting device includes: a light emitting element that contains the above-described phosphor; and an excitation source.

摘要： A fine metal linear body is provided in which the sintering temperature is lower than that in conventional examples. The fine metal linear body has a length of 0.5 to 200 µm and a thickness of 30 nm to 10 µm. When a length of a crystal of a metal constituting the fine metal linear body, in a direction in which the fine metal linear body extends, is taken as X, and a length thereof in a direction orthogonal to the direction is taken as Y, an X/Y value, which is a ratio of the X to the Y, is 4 or less, in three boundary regions when dividing the length of the fine metal linear body into four equal parts along the extending direction.
