Physical, Structural, and Luminescence Studies of Nd~(3+) Doped MgO-ZnO Borate Glass

摘要

A series of borate glass of the system xNd_2O_3-5MgO-20ZnO-(75 - x)B_2O_3, where x = 0.5, 1.0, 1.5, 2.0, and 2.5 was successfully fabricated using melt quench method. The properties of the glass were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR), absorption and luminescence spectra. The upconversion properties of Nd~(3+) doped borate glass were observed by using 574 nm excitation wavelength corresponding to ~4I_(15/2) → ~2H_(114/2) transition. The emission bands centered at 460, 500 and 620 nm which corresponding to the Nd~(3+) transitions, ~4F_(7/2) → ~4I_(15/2), ~2H_(11/2) → ~4I_(15/2), and ~4F_(9/2) → ~4I_(15/2) respectively were observed at room temperature. The presence of Nd~(3+) in borate based glass could intensify the upconversion luminescence spectra as it can potentially be used as host materials for upconversion lasers.
