Abstract

Sm3+doped barium borate glass (60B2O3 + 39.7BaCO3 + 0.3Sm2O3) wassynthesizedand studiedbyvarious spectroscopic techniques. UV-absorption data were used to calculate the Urbach energy (Eu) and optical band gap energies (Eg) of the glasses. In this work, the excitation-dependent photoemission properties of the prepared glass were studied. The photoluminescence (PL) spectraexhibits the radiative transitions inSm3+ barium borate (SBB) glass and the radiative transitions of Sm3+ ions from 4G5/2 to 6H9/2,6H7/2, and 6H5/2, attributes in the emissions at 649, 602, and 566 nm. The PL decay study with the Inokuti-Hirayama model, indicates the different multipolar interaction mechanism.The study determines critical transfer distance(Rc), the energy transfer parameter (Q), and donor-acceptor interaction parameter (CDA). The thermoluminescence (TL)kinetic parameters of glass were studied by the peak shape method. From the PL spectra, colorimetric parameters were evaluated, shows the glass could be used for various optoelectronic applications.
