- the inventors of the present application have further studied the method of preventing the aggregation of the composite nanoparticles, and as a result, the aggregation of the composite nanoparticles was determined by changing the order of addition of the reagents to Na citrate, MPS, anion, and the cation. It has been found that a composite nanoparticle that is prevented and has good dispersibility can be obtained. A film of silica of about 1 nm was formed on the surface of the composite nanoparticles.
- the core portion of the composite nanoparticle of the present invention and a surface-modifying portion that covers the surface of the core portion to modify the surface are simultaneously formed by the coprecipitation method in the presence of the dispersion stabilizer and the surface modifying agent. And a step of forming a nano-sized insulating shell part on the surface of the surface modification layer.
- the phosphor ZnS: Mn 2+ is synthesized by a method for producing composite nanoparticles. This indicates that nanocrystal 5 is formed. As shown in FIG. 3, the nanocomposite nanoparticles maintained a very stable dispersion state, and did not precipitate over time. The addition of both Na and MPS forms fairly stable ZnS: Mn2 + nanoparticles.
- Sodium citrate added as a dispersion stabilizer releases Na + in the solution and becomes an ion with multiple COOs. This adsorbs to the phosphor particles, causing a negative charge on the particle surface, which increases the dispersibility of the solution due to electrostatic repulsion.
- the terminal SH chemically bonds to the surface of the ZnS: Mn nanoparticle to prevent direct contact between the nanoparticles.
- MPS alone was able to synthesize a sample with good dispersibility using MPS. Further, the dispersibility of the particles was improved by adding Na citrate, so that the surface modification by MPS and the suppression of particle growth were effectively performed, and as a result, the effect of stabilization was enhanced.
- the change in the absorption spectrum after the synthesis is small and it is focused. This also shows that the growth and aggregation of the particles hardly occur.
- Manufactured by the aforementioned manufacturing method was Z n S: Mn 2+ / S I_ ⁇ 2 37 * more distributed resistance that prevents aggregation by stopping the growth of S i 0 2 layers of shell of the click Risutaru phosphor

- the phosphor particles dispersed in the reaction vessel 13 maintained a stable suspension state even after 14 days, and did not aggregate. That is, it is assumed that the phosphor particles do not precipitate in the reaction vessel 13 and the particles dispersed in the reaction vessel 13 are nano-sized.
- FIG. 4 shows a light emitting spectrum when the Zns: Mn 2+ / Si 2 phosphor in the suspension state is made to emit light by ultraviolet rays.
- nano-sized phosphor particles which are not aggregated in the reaction vessel 13 and dispersed while maintaining a stable suspension state are collected by sedimentation by centrifugation and dried at 50 ° C. Accordingly, nanocrystal phosphor powder Z n S: Mn / S I_ ⁇ 2 was obtained.
