针对一般光反应器的不足,双面金属包覆波导能够把光耦合进入导波层中激发出超高阶导膜,波导中入射波与反射波相互叠加形成驻波,继而在导波层中出现一系列的光能量增强点(被认为是光陷阱点).基于这种光学特性,设计了一种新颖的液芯双面金属包覆波导光反应器.采用含有二价铁离子和三价铁离子的混合盐溶液充当导波层,激光耦合进入导波层中两小时后,在该种特定光场分布的作用下,制备出了合成产物.通过对产物的分析,确定合成产物为磁铁矿γ-Fe2O3.

Double metal cladding waveguide can couple the light into the guiding layer to inspire the ultrahigh order modes, the incident waves overlap with the reflected waves to form standing waves in the guiding layer, and then a series of enhanced power points which are considered to be optical trapping points are formed. Based on this optical property, aiming at the shortcomings of the general optical reactor, we had designed a novel liquid-core waveguide optical reactor. Aqueous Fe2+/Fe3+ salt solutions in the hollow-core acted as the guiding layer of the reactor. Two hours after the light had coupled into the guiding layer under the special optical field, the synthetic products had been prepared. Depending on some analysis toward the products, it is sure that they are crystalline magnetiteγ-Fe2O3.
