Mn掺杂ZnO(以下简称ZnO:Mn)稀磁半导体的磁性根源之一来源于晶体内部的晶化程度及晶格畸变.本文利用磁控溅射方法在玻璃衬底上室温沉积了ZnO,ZnO:Mn以及Mn和N共掺杂(以下简称ZnO:(Mn,N))薄膜.同时结合XRD衍射谱,SEM图和Raman光谱分析了掺入Mn和N元素后ZnO薄膜的结构变化.Raman光谱结果显示,在引入Mn元素以及进一步引...
Resonance Raman spectra of the MnII-NO moiety in synthetic nitrosyl manganese heme complexes with and without steric hindrance are reported. The "strapped" hemes having a hydrocarbon strap (variable length) across one face of the heme hinder the perpendicular bonding of a linear ligand. These ...
Determinative Role of the Jahn-Teller Disorder in the Raman Scattering of Mixed-Valence Manganites The mixed-valence perovskitelike manganites are characterized by unique interrelation of Jahn-Teller distortions, electric and magnetic properties. The Jah... MN Iliev,MV Abrashev,VN Popov,... 被引量...
S4 (ESI†), the Raman spectrum shows characteristic D and G bands at 1345.96 and 1579.34 cm−1, respectively, typical for the disordered structure of hard carbon. Additionally, the N2 adsorption–desorption isotherms of MSNC was revealed in Fig. S5a (ESI†). The pore size distribution ...
Hexa-ammine complexes, Mn(NH 3) 6 X 2 ( X = Cl, Br), have been synthesized by ammoniation of the corresponding transition metal halide and characterized by Powder X-ray diffraction (PXRD) and Raman spectroscopy. The hexa-ammine complexes are isostructura
