摘要：An efficient CuO‐modified zeolitic imidazolate framework‐9(ZIF‐9)photocatalyst is successfully prepared at room temperature under mild *** is observed that the ZIF‐9/CuO photocatalyst is effective for H2generation under visible light with sacrificial agent *** the CuO is introduced,the photocatalytic properties of ZIF‐9are greatly improved and when the content of CuO is40%,the photocatalytic activity reaches a maximum of78.74μmol *** results from the200–300nm cube structure of ZIF‐9being able to adsorb more dye molecules and the CuO,which connects with ZIF‐9,greatly improving the electronic transmission ***,the interaction between the dye molecule Eosin Y(EY)and the catalyst is also studied by transient fluorescence spectroscopy.A series of characterizations,such as SEM,TEM,XPS,XRD,UV‐vis,FTIR,transient fluorescence and photocurrent,are conducted,and the results are in good agreement with the experimental *** addition,the possible reaction mechanism over EY‐sensitized ZIF‐9/CuO under visible light irradiation is proposed.

摘要：根据薄膜的偏振效应,运用Essential Macleod光学薄膜设计软件,完成DVD棱镜中消偏振二向色膜的设计,并采用光控法精确控制膜层厚度,制备出了满足客户要求的消偏振分光棱镜。残余应力大的薄膜容易产生脱膜现象,使得薄膜失去所需功能。为了消除薄膜应力,从膜料之间应力匹配关系及制备工艺2个方面,提出了控制薄膜应力的设计思想,并对其影响进行了讨论,利用镀膜前后光圈变化来反映膜层应力的大小。制备过程中,通过设计制作可调工装来改变镀膜有效孔径,通过调节标准块来满足非常严格的镀膜有效孔径要求。本文给出了该棱镜的消偏振膜系的设计和试验结果。
