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。 Nano-or micro-scaled Bi2S3 crystals（1） were synthesized by EDTA（ ethylenediamine tet- ra-acetic acid ） -assisted hydrothermal method from Bi（ NO3 ）3·5H20 and Na2S203 · 5H20. The structure, topography and spectrum property of I 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.
