Versuchsvorschrift

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), trioctylphosphine oxide (3.866 g) and trioctylphosphine (3.7 g) were added. Then, a 0.05 M aqueous solution of sodium sulfide (10 ml) was added. After the system was reacted at 90° C. for 3 h, a clear yellow sol containing CdS nanoparticle was obtained. Said sol has the typical exciton absorption peak of CdS nanoparticle, can result in a quantum size effect and emit a fairly strong blue light under the irradiation of a UV lamp.
