摘要
Provided are a method of producing a thiogallate-based fluorescent material, a method of producing a light-emitting device, a thiogallate-based fluorescent material, and a light-emitting device. The method of producing a thiogallate-based fluorescent material includes preparing a first solution containing at least one M1 ion selected from the group consisting of Sr, Be, Mg, Ca, Ba and Zn, and at least one M2 ion selected from the group consisting of Eu and Ce, and a second solution containing a sulfite ion, simultaneously supplying the first solution and the second solution to a reactor to obtain a powder containing a sulfite that contains an element M1 and an element M2, mixing a raw material that contains the powder containing the sulfite that contains the element M1 and the element M2 and a powder containing a gallium compound, with lithium chloride to obtain a mixture, and heat-treating the mixture to obtain a thiogallate-based fluorescent material.
