実験手順
Cadmium oxide (0.127 g, 1 mmol) and tetradecyl carboxylic acid (0.500 g) were reacted at 220° C. for 10 min, cooled to 90° C., a cadmium tetradecylcarboxylate (precursor) was formed. Into said system, toluene (10 ml) and mercapto-etanol (0.6 ml) was 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 mercaptoethanol-coated CdSe nanoparticles was obtained. Said sol can be dispersed stably in water, has a typical exciton absorption peak of the CdSe nanoparticles, can result in a quantum size effect and emit a fairly strong green light under the irradiation of a UV lamp.
