Characterization of Zn0. 95Mn0.05O synthesized by polymeric precursors
(2008-12-01)
This paper discusses the preparation and characterization of Zn 0.95Mn0.05O phase obtained by the polymeric precursor method for DMS applications. The as-obtained powders were calcined between 500 to 800°C and characterized ...
