ZnS nanostructures with different dimensions and structure-related properties were reviewed in this paper.The crystallization of nanostructures from 0D,1D to3D,as well as the heterogonous counterparts,was summarized in the aspect of zinc blende,wurtzite structure,and their combinations.Furthermore,the structure-related energy bands and the corresponding photoelectric properties of ZnS nanostructures were also focused,in which we made a brief summary of the co-relations between photoluminescence and crystallography,especially the defectrelated luminescence properties of ZnS nanocrystal.
It is the result of a systemic study about uniform hematite nanopallets with length of about 100 nm, width of about 30 nm, and thickness of less than 10 nm. The sample has superparamagnetic(SPM) properties above the blocking temperature of ～16 K. The temperature dependence of magnetization was well fitted by Bloch T^(3/2) law considering the dipolar interaction of the particles. The field dependence of magnetization was fitted with revised Langevin equation.The magnetization of the weak ferromagnetic(WF) canted spins contributes to the linear portion in the high field region;the surface uncompensated spins and the parasitic ferromagnetic moments due to the canted spins both contribute to the particle moments and the superparamagnetic behavior.
