47 - 220PVA-Assisted Synthesis and Characterization of CdSe and CdTeNanowires. — Nanowires of the title compounds are synthesized solvother-mally in the presence of poly(vinyl alcohol) from a mixture of Cd(NO3)2,Na2SeO3 or K2TeO3, H2O, and en (autoclave, 160 or 180 ◦C, 6–15 d). Thesamples are characterized by XRD and TEM. In this process, the temperatureis the main factor determining the structure of the nanowires. The preparedsamples are predominantly in zinc blende form. Poly(vinyl alcohol) plays animportant role in the formation of the nanowires attributed to promoting theoriented attachment growth under solvothermal conditions. — (YANG, QING;TANG, KAIBIN; WANG, CHUNRUI; QIAN, YITAI; ZHANG, SHUYUAN; J.Phys.
