Optical, electrical, mechanical properties of Pr3+ and Yb3+ doped phosphate glasses.

The rare earth Pr3+ and Yb3+ doped phosphate glass were prepared by quenching method using electrical muful furnace. The optical band gap of rare earth Pr3+ and Yb3+ doped phosphate glass were studied. The dielectric permittivity, dielectric loss and electrical conductivity of the prepared samples have been studied using LCR meter with different frequencies at room temperature. The Vickers hardness number, brittle index, yield strength, fracture toughness of the rare earth Pr3+ and Yb3+ doped phosphate glasses were also calculated. The nonlinear optical parameters such as third order nonlinear coefficient and nonlinear refractive index were estimated using Z-scan method. The magnetic property of the Pr3+ and Yb3+ doped phosphate glass was studied using VSM analysis. The electro chemical properties of Pr3+ and Yb3+ doped phosphate glass electrodes in 5 M KOH electrolyte were studied using cyclic voltammetry, Galvanostatic charge–discharge and electrochemical impedance spectroscopy. The specific capacitance, energy density and capacity retention of Pr3+ and Yb3+ doped phosphate glasses were calculated. [ABSTRACT FROM AUTHOR]
