文摘
Nanocrystallites of nonstoichiometric copper selenide (Cu2-xSe) and stoichiometric copper selenides (
-CuSe andCu3Se2) were synthesized in different solutions via sonochemical irradiation at room temperature. The influence ofsolvents, surfactants, and ultrasonic irradiation on the morphology and phase of products has been investigated.The morphological difference of the products was mainly affected by the solvents and surfactants, which canself-aggregate into lamellar structures or microemulsions, and then these unique structures can act as bothsupramolecular template and microreactor to direct the growth of copper selenides. On the other hand, it was alsofound that the sonochemical irradiation and solvents played an important role in the formation of different phasesof copper selenides. The proposed formation mechanism of copper selenides is discussed.
