Abstract: A semiconductor nanoparticle, a method of preparing the semiconductor nanoparticle, and an electroluminescent device including the semiconductor nanoparticle. The method of preparing the semiconductor nanoparticle includes contacting a zinc precursor and a sulfur precursor in the presence of a first particle at a predetermined temperature to form a semiconductor nanocrystal layer containing zinc sulfide on the first particle, wherein the first particle includes a Group II-VI compound including zinc, selenium, and, optionally, tellurium, or the first particle includes a Group III-V compound including indium and phosphorus. The predetermined temperature includes (e.g., is) a temperature (e.g., a reaction temperature) of greater than 300° C. and less than or equal to about 380° C., and the sulfur precursor includes a thiol compound of C3 (e.g. C9) to C50 or a combination thereof.
