transmission electron microscopy, and X-ray diffraction. Two complexes were highly similar in their patterns and crystallinities with the characterized particle size range 23.16-23.31 nm. Energy gaps of the two complexes NS Na3La(III)-(L1)2 and NS Na3La(III)-(L2)2 were found to be 2.09 and 2.33 eV, respectively. Linear and calculated nonlinear optical properties have been studied for the two complexes. The
本研究集中在基于镧离子从具有两个芳基-偶氮-邻苯三酚配体的溶液直接层沉积到玻璃基板表面上的基础上,组装两个新的薄膜。组装的镧(III)配合物通过不同的技术进行了表征,包括热重分析,酸消解和络合滴定法进行金属分析,傅立叶红外光谱,透射电子显微镜和X射线衍射。两种配合物的图案和结晶度高度相似,特征粒径范围为23.16-23.31 nm。发现两种配合物NS Na3La(III)-(L1)2和NS Na3La(III)-(L2)2的能隙分别为2.09和2.33 eV。已经研究了两种络合物的线性和计算的非线性光学性质。
