Luminescence nanoparticle improving light emitting efficiency comprising zinc-silver-indium-sulfide and the method for manufacturing thereof by combichemistry

摘要

invention - - - ((Zn_xAg_yIn_z)S₂)(0.15 x 0.25, 0.35 y 0.45, 0.35 z 0.45, x + y + z = 1) is a composition of the nanoparticles and the method having the light emission. To this end, the present invention is a zinc-silver-stage constituting the library for the composition of the indium (step 1); Step introducing zinc precursor, silver precursor and the indium precursor and the vulcanizing agent according to the library configured in the above step 1 to each of the different reactor containing the solvent for preparing a metal precursor solution (step 2); Irradiating ultrasonic waves in the metal precursor solution in each reactor was prepared as described in Step 2 (Step 3); After ultrasonic irradiation in the stage 3 alcohol-based solvent, by addition of a hydrocarbon solvent, mixed solvents of the foregoing zinc-silver-indium-sulfide to precipitate the particles (step 4); Removing the supernatant and in the step 4 the particles are precipitated (step 5), and the supernatant was removed as described in Step 5 zinc-silver-indium-sulfide confirming the luminescence properties of the nanoparticles (step 6) ; provides a method comprising the. According to the present invention can be rapidly manufacturing a light emitting nanoparticles with various compositions, can be found by checking the light emission characteristics of the light emitting nano-particles is optimized to the desired composition. ;
