In this study is used the Hot-Wall Epitaxy System produce CdSSe/ZnSe multilayers ,and used of Hot-Wall Epitaxy System’s high vacuum and can strip the whole of the baking temperature thermal annealing samples, by this to find out ZnSe and Cds thin films in the best flat extent , and conductive to growth the light-emitting layers.Observation ZnSe、 CdS、CdSSe’s emission wavelength of different thickness.Use the ZnSe emission blue light and CdSSe emission yellow light to try to produce multilayer samples,and try to reconcile into white light.
