ظروف التفاعل

الإجراء التجريبي

Zinc oxide (0.08 g, 1 mmol) and tetradecylcarboxylic acid (0.500 g) were reacted at 220° C for 10 min, cooled to 90° C., then a zinc tetradecylcarboxylate (precursor) was formed. Into said system, toluene (10 ml), trioctylphosphine oxide (3.866 g) and trioctylphosphine (3.7 g) were added. Then a 0.05M aqueous solution of sodium hydrogen selenide (10 ml) was added. After the system was reacted at 90° C. for 3 h, a clear yellow sol containing the ZnSe nanoparticles was obtained. Said sol has a typical exciton absorption peak of the ZnSe nanoparticles, can result in a quantum size effect and emit a fairly strong blue light under the irradiation of a UV lamp.
