| Abstract | Glass samples with varying concentrations of Nd2O3 were prepared by using the melt-quenching technique. The absorptionspectra and the NIR emission spectra of Nd3+-doped sodium barium borate oxyfluoride glasses were investigated in order tounderstand the e ect of di erent Nd2O3 concentrations. The absorption spectra exhibited eight peaks in the visible light rangeand three peaks in NIR range. All of transition peaks were found to start from a transition ground state of 4I9=2 and moveto excited states. The transition of 4G5=2+2G7=2 gave the largest peak when compared to the other transition peaks that wereobserved. The absorbance of the glass samples was seen to increase as a function of Nd2O3 concentration. The emissionspectra were found at wavelengths of 1071 nm (4F3=2 --> 4I11=2) and 1343 (4F3=2 --> 4I13=2) nm. The transition 4F3=2 --> 4I11=2shows that the material has great potential for use as a laser material as it has a wavelength of 1071 nm. The emission intensitywas seen to increase with Nd2O3 concentration up to 0.50 mol%. Increasing the concentration beyond this point led to a fall inemission intensity. It was thought that this was due to the concentration quenching e ect. |
