Superconducting Compound

The high temperature superconductor’s compounds are one of the hot spot field of science, due to their applications in industries. Hg0.8Sb0.2Ba2Ca2Cu3O8+δ and Hg0.8Sb0.2Ba2Ca1Cu2O6+δ, were manufactured using a doable-step of solid state reaction method. The samples were sintered at 800 ° C. The transition temperatures Tc are found from electrically resistively by using four probe techniques. The resistivity become zero when the transition temperature Tc(offset) have 131 and 119 K, and the onset temperature Tc(onset) have 139 K for Hg0.8Sb0.2Ba2Ca2Cu3O8+δ and 132 K for Hg0.8Sb0.2Ba2Ca1Cu2O6+δ. Analysis of X-ray diffraction showed a tetragonal structure with lattice parameters changes for all samples.

In this paper, Ba3MgSi2O8: Eu2+, Mn2+ phosphor was synthesized by the sol-gel method and high temperature solid-state reaction method. The structure and emission spectrum excited by near violet light were investigated. we studied the process of phase change in roasting and determined the approximate crystallization temperature of Ba3MgSi2O8: Eu2+, Mn2+ phosphors. Our results demonstrate that 514 nm emission bands were from Eu2+ ions replacing of the sites of Ba2+ in Ba2SiO4. 440 nm emission bands originated from Eu2+ ions substituting the sites of Ba2+ in Ba3MgSi2O8, corresponded to 4f65d1→4f7 transition of Eu2+ ions. 615 nm emission bands ascribed to Mn2+ ions taking place of the sites of Mg2+ ions, corresponded to 4T→6A red launch of Mn2+ ions.
