| 摘 要： | 以Bi(NO3)3·5H2O和Na2S2O3·5H2O为原料,用乙二胺四乙酸(EDTA)辅助水热法合成了纳米或微米级的Bi2S3晶体(1),其结构、形貌和光谱性能经XRD,FE-SEM和UV-Vis表征。结果表明:溶液的pH对1的形貌有显著的影响,随着pH的增大,1由纳米棒组成的微米球逐渐转变为微米级片状结构;1出现蓝移。

| Abstract: | Nano-or micro-scaled Bi2S3 crystals(1) were synthesized by EDTA(ethylenediamine tetra-acetic acid)-assisted hydrothermal method from Bi(NO3)3·5H2O and Na2S2O3·5H2O.The structure,topography and spectrum property of 1 were characterized by XRD,FE-SEM and UV-Vis.The results showed that the pH value of solution played a key role in the formation of 1 topography,the micro-spheres composed of nanorods transform into micro-plate structures as pH value increasing.1 shows blue shift. |
