摘要 |
<p>The present invention relates to light-emitting nanoparticles having improved light emission characteristics and having a zinc-silver-indium-sulfide composition and to a method for preparing same using combinatorial chemistry. To this end, the present invention provides light-emitting nanoparticles having improved light emission characteristics and having a zinc-silver-indium-sulfide ((ZnxAgyInz)S2)(0<=x<=1, 0<=y<=1, 0.1<=z<=1, x+y+z=1) composition. Furthermore, the present invention provides a method for preparing the light-emitting nanoparticles, comprising: a step (step 1) of constructing a library for a zinc-silver-indium composition; a step (step 2) of introducing a zinc precursor, a silver precursor and an indium precursor and a vulcanizing agent based on the library constructed in step 1 to each of different reactors including a solvent to prepare a metal precursor solution; a step (step 3) of irradiating the metal precursor solution with ultrasonic waves in each reactor prepared by step 2; a step (step 4) of adding an alcohol-based solvent, a hydrocarbon-based solvent or a mixture solvent thereof to the metal precursor solution after the ultrasonic wave irradiation of step 3 so as to precipitate zinc-silver-indium-sulfide particles; a step (step 5) of removing supernatant after the precipitation of the particles in step 4; and a step (step 6) of checking the light emission characteristics of the zinc-silver-indium-sulfide nanoparticles from which the supernatant is removed in step 5. According to the present invention, light-emitting nanoparticles having various compositions can be quickly prepared, and light emission characteristics are checked to find light-emitting nanoparticles optimized to a desired composition.</p> |
