Abstract
Semiconductor Ag2CrO4 quasi-nanorods and nanowires have been successfully prepared through novel emulsion–liquid membrane technology. The membrane phase in this system consists of Span-80 as the surfactant, N7301 as the carrier (or free carrier), and kerosene as the solvent. The internal aqueous phase is 0.1 M AgNO3 and the external aqueous phase is 0.1 M K2Cr2O7. Under the conditions of Roi = 2.0, Rew = 0.5, [Span-80] = 6% (v/v), and room temperature, Ag2CrO4 quasi-nanorods with diameters of 180–300 nm and lengths of up to 2300 nm, or nanowires with diameters of 15–25 nm and lengths of up to 1000 nm, were obtained in the presence or absence of 5% (v/v) N7301, respectively. X-Ray diffraction and transmission electron microscopy were used to characterize the structure and morphology of the Ag2CrO4 quasi-nanorods and nanowires. In addition, the photoluminescence spectrum showed strong emissions.
