摘　　要：利用大葱生物膜内外有别的结构特性模拟生物矿化过程,在室温下同步诱导合成出颗粒状和球状两种不同形貌的硒化汞材料,前者尺寸约为200 nm的大纳米颗粒,该产物可能是由尺寸约30 nm的小纳米粒子组装而成;后者尺寸约为3μm的高度致密的带花边的实心圆球,该产物可能是自发生长或由直径约1μm的小球组装而成.其结构均为立方相,晶格常数为0.608 nm.通过紫外可见光谱(UV Vis)和荧光光谱(Fluorescence,FL)对产物的光学性质进行了研究.初步探讨了硒化汞的合成机理.Mercury selenide microsphere and nanoparticle were synchronously synthesized with the green Chinese onion as the living biotemplate. The result indicates that the former large spheres with the diameter of 3 μm are possibly self-vegetal or packaged by those with that of 1 μm, and the latter with the size of 200 nm are possibly packaged by the nanoparticles with the size of 30 nm, and both of them have a cubic structure with a cell parameter is 0. 608 nm. Their optical properties were investigated by both UV-Vis and FL spectra. In addition,possible mechanisms are investigated.
