Spectroscopic Properties and Judd-Ofelt Analysis of Dy³⁺ in Lithium Lanthanum Borate Glass for Laser Medium Application

Abstract:

Dysprosium doped lithium lanthanum borate glasses (LiLaB:Dy³⁺) were prepared by the melt quenching technique, varying the Dy₂O₃ doped concentration from 0.00 to 1.50 mol%. The absorption spectra showed that LiLaB:Dy³⁺ glass absorbed photon in visible light and near infrared region. From the excitation of 388 nm, this glass emitted the photon with 483, 575, 664 and 753 nm wavelength. The intensity of emission increased with increasing of Dy₂O₃ concentration until 1.0 mol%, after that it decreased. The Judd-Ofelt (J-O) analysis was applied to 1.0 mol% doped glass to investigate the J-O parameter, radiative transition possibility and stimulated emission cross section. These values were interpreted to the ability of laser gain medium.
