The Effect of Variation Concentration Nd<sup>3+</sup> Ions on Physical and Optical Properties of TZBN Glass

Abstract

This study aims to determine the optical and physical properties of TZBN:Nd glass with the composition (mol%) 60TeO2-2Bi2O3-(34-x)ZnO-4Na2O-xNd2O3 with variation of doping x = 0.5; 1.0; 1.5; 2.0. Fabrication has been done by using the melt-quenching technique. Characterization of tellurite glass covering density, refractive index and absorption spectrum of glass. Density of glass have been measured using the Archimedes method. Refractive index of glass have been measured using the Brewster angle at wavelength 746.191 nm. Absorption spectrum measurements using UV-Vis-NIR spectrophotometer Perkin Elmer Lambda 25 in the region of 200-1100 nm. The results of characterization show that density / physical characteristics of glass did not increase when the concentration of ions Nd3+ to TZBN:Nd glass increased. The refractive index of glass will increase as the concentration of ions Nd3+ to TZBN:Nd glass increased. Based on the results of UV-Vis-NIR spectroscopy measurements shows that there are nine significant spectra have been observed in the region of 200-1100 nm, such as at a wavelength of 431 nm, 474 nm, 515 nm, 527 nm, 585 nm, 684 nm, 749 nm, 805 nm, and 878 nm and the highest absorption peak is at a wavelength of 585 nm.
