). The oxidation state of Mn in ZnSe nanocrystal was found using electron spin resonance (ESR) spectrum. The room temperature luminescence measurements show the peaks corresponding to both bandgap of the material and Mn in ZnSe. Key words:Ⅱ-Ⅵ semiconductors; nanocrystalline materials; electron spin resonance; [全文内容正在添加中] ......
method was used to obtain the NiO/NiFe2O4 composite coating. DSC, SEM, EDS and XRD analysis methods were used to analyze the influence of pre-oxidation temperature on the coating structure, morphology, elemental distribution and composition of the phase, and forming reaction mechanism and kinetics of the coating were also discussed. The results show that by high temperature diffusion processes......
