Physical and optical properties of bismuth borate glass doped with different rare earth ions A 2 O 3 (A= La, Ce, Nd, Sm)

Abstract

The physical, structural, and optical features of Bi2O3-B2O3-A2O3 (A = La, Ce, Nd, Sm)-based glasses were examined by measuring the density, optical band gap, volume access, spacing between boron atoms, and infrared (FTIR) and optical analyses. To obtain the optical band gap (Eopt), we applied the extinction coefficient approach. Our work demonstrates how the optical band gap forms and how atomic numbers correlate with all the physical attributes. The fiber ability of the research glasses was good. The glass samples studied are ideal for use as the fiber core material, and The Nd3+ connection is an ionic bond, whereas the Sm3+ link is a covalent bond, according to the bonding parameter. The optimal ions for effective luminescence were determined using spectroscopic techniques.
