Neodymium Doped Borate Glasses for NIR Emitting Solid State Device Applications

Abstract

Objectives: To investigate the effect of B 2 O 3 replaced by Nd 2 O 3 studies on the spectroscopic characteristics of trivalent neodymium (Nd 3+ )-doped glasses using XRD, FTIR, absorption, and emission spectroscopy. Methods: The glasses were synthesized using the conventional melt quenching technique at 1150 0 C. The amorphous nature of the samples was confirmed by x-ray diffraction studies. Findings: The addition of Nd 2 O 3 concentration affects the absorption and emission properties of the Nd 3+ ion measured in the near-infrared luminescence range from 0.9µm, 1.06 µm, and 1.36µm associated with the 4 F 3/2 → 4 I J (J = 9/2, 11/2, 13/2) transitions. Novelty: The novelty of the present work is to fully understand and characterize the luminescence of Nd 3+ doped borate bulk glasses with different doping concentrations. So as to gain an insight of 1.06 µm corresponding to 4 F 3/2 → 4 F 11/2 transition, these glasses are highly potential one which is an applicable to NIR emitting solid state device.
