A comparative study on lanthanum oxide and holmium oxide doped borate glasses

We have synthesized La2O3 and Ho2О3 doped borate glasses using conventional rapid melt quench method. The amorphous nature was identified using the XRD pattern. Photoluminescence spectrum and IR spectrum were used to analyze the spectral properties and differentiate the various vibrational modes. Also Raman spectroscopy of La2O3 and Ho2О3 doped borate glass was studied. The electrical properties such as the dielectric constant and the dielectric loss, of the La2O3 and Ho2О3 doped borate glass were studied at different frequencies and different temperatures.
