Method and device for preparing zinc cadmium sulfide selenide nanowires with fluorescence changing from ultraviolet to red

The invention discloses a method and device for preparing zinc cadmium sulfide selenide nanowires with fluorescence changing from ultraviolet to red. The method is characterized by adopting high temperature to volatilize zinc sulfide in a zinc sulfide volatilization region and cadmium selenide in a cadmium selenide volatilization region, adopting a sedimentation method to grow zinc cadmium sulfide selenide nanowires on a growth carrier in a growth region in the environments of certain vacuum and airflow and ensuring the ratio of such components of the nanowires as the zinc sulfide and the cadmium selenide to continuously change from 1:0 to 0:1 through movement of the growth carrier in the growth region. The device comprises a high temperature furnace, a box body, a vacuum pump, a gas cylinder and a moving device, wherein a connecting lever suspending in the box body is arranged inside the box body; two containers are arranged on the connecting lever; a carrier platform installed on the box body is arranged at the same side of the two containers; and the moving device can be utilized to move the box body and the carrier platform at certain speed. The fluorescence spectra of the zinc cadmium sulfide selenide nanowires prepared by the method and device can continuously change from ultraviolet to red in a monotone manner.
