Luminescence properties and energy transfer of Nd- Er/ Nd-Pr co-doped LFP glasses system.

The motivation for this research is that the emission spectra using directly pumped laser diodes have not yet been found. We want to explore the luminescence properties of a co-doped laser material utilizing a diode laser as an optical pump. The research method used standard melt-quench and was stimulated by a laser diode (808 and 980 nm).

Structural and spectroscopic properties of Er doped sodium lithium borate glasses.

The trivalent erbium (Er doped sodium lithium borate glass with composition (65-x)BO-15NaO-10PbO-5ZnO-5LiO-xErO have been successfully fabricated by melt-quench technique. The structural properties were investigated by X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR). The absorption and luminescence spectra of glass samples were measured to determine the spectroscopic properties.
