Conditions

Temperature: 90 °C

Procedure

Cadmium oxide (0.127 g, 1 mmol) and stearic acid (0.500 g) were reacted at 220° C. for 10 min, cooled to 90° C., then a cadmium stearate (precursor) was formed. Into said system, toluene (10 ml), trioctylphosphine oxide (3.866 g) and trioctylphosphine (3.7 g) were added. Then a 0.05M 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 nanoparticles was obtained. Said sol has the typical excition absorption peak, can result in a quantum size effect and emit a fairly strong blue light under the irradiation of a UV lamp.
