| Mineralogical characteristics of inartificial chrysotile nano-tubes were researched. And then, electrochemistry-method was adopted for the first time to assemble CdS quantum-dots in it. Artificial chrysotile was composed, and its crystal structure and mineralogical charters were inextenso researched compare with inartificial chrysotile. CdS and ZnS quantum-dots were assembled in inartificial and artificial chrysotile nano-tubes by ultrasonic chemistry-method for the first time, respectively, and the assembled samples underwent a series of testing and researches. The research results are as below. The assemble ratio of Electrochemistry-method was about 1%. Nano-tubes diameter of artificial chrysotile (-10nm) was lager than that of inartificial chrysotile (-5nm), their average length was 150nm and tubes were unclosed. Assemble rations of ultrasonic chemistry-method were lager than that of electrochemistry-method, and the ratios of artificial chrysotile were larger than that of inartificial chrysotile, the ration of artificial chrysotile adopted ultrasonic-method even reached more than 30% at best. The assembled CdS and ZnS quantum-dots were all β kind with cubic structure, and the average crystal granularity were round about 4nm. Due to the quantum confinement effect and the dielectric confinement effect which caused by large difference between permittivity of the semiconductor quantum-dots and chrysotile, a certain extent red shift and blue shift were appeared in assembled CdS and ZnS quantum-dots. At last, the assemble mechanisms of electrochemistry-method and ultrasonic chemistry-method were discussed. |
