EXAMPLE - Indium triacetate (0.75 mmol), palmitic acid (PA) (2.25 mmol), and 1-octadecene (15 ml) were agitated at 120 degrees C for one hour, and to that mixture tris(trimethylsilyl)phosphine (TMSP) (0.375 mmol) was injected to prepare a solution A. Similarly indium triacetate (0.6 mmol), PA (1.8 mmol), and 1-octadecene (30 ml) were combined in a separate flask, the mixture was agitated at 120 degrees C for one hour and then placed under a nitrogen atmosphere and heated to 280 degrees C. Then, TMSP (0.3 mmol) was injected into the flask and after 40 minutes and to that, solution A (11 ml) was added. After 30 minutes, the resulting mixture was cooled to room temperature and then separated by the addition of acetone (35 ml). The acetone solution was removed, and worked up to obtain indium phosphide/zinc sulfide semiconductor nanocrystal. Then, the obtained semiconductor nanocrystal (100 parts by weight) was mixed with polydimethylsiloxane (1000 parts by weight) and triethylsilane (100 parts by weight) to obtain resin particle composition.
