실험 절차
Cadmium oxide (0.127 g, 1 mmol) and tetradecylcarboxylic acid (0.500 g) were reacted at 220° C. for 10 min, cooled to 90° C., then a cadmium tetradecylcarboxylate (precursor) was formed. Into said system, toluene (10 ml), dodecyl mercaptan (1.2 ml) and tetraoctylammonium bromide (0.546 g, as a phase-transfer catalyst) and trioctylphosphine (3.7 g) were added. Then a 0.05M aqueous solution of sodium hydrogen selenide (10 ml) was added. After the system was reacted at 90° C. for 3 h, a red sol containing the dodecyl mercaptan-coated CdSe nanoparticles was obtained. The sol has a typical exciton absorption peak of the ZnSe nanoparticles, can result in a quantum size effect and emit a fairly strong green light under the irradiation of a UV lamp.
