    摘要: Disclosed herein is a carboxylic ester dispersant shown in the following Formula 1 and a sulfide phosphor paste composition containing the dispersant. The dispersant improves the dispersibility of the sulfide phosphor paste composition and prevents oxidation by a solvent, thus improving processability and the luminescent properties of a phosphor film made from the paste and of a display produced using the film. In Formula 1, n is 1-20.

    摘要: A sulfide phosphor paste composition comprising a sulfur-containing dispersant, and a fluorescent film prepared therefrom, are provided. The sulfur-containing dispersant has a dual head structure containing both a carboxyl group and a thiol group or a structure containing a thiol or thiophene group as a head group. An oligomeric sulfur-containing dispersant is also provided. Adsorption of the dispersant on the surface of the sulfide phosphor prevents aggregation of the phosphor particles, and thereby improves the dispersibility of the sulfide phosphor paste composition, the homogeneity of the phosphor in the paste composition, and the density of a film produced from the paste composition. Fluorescent films and display devices produced from the phosphor paste composition exhibit improved luminescent properties and excellent processability.
