Abstract
The novel gadolinium borosilicate glasses doped with 1.0 mol% of Dy2O3 concentration in the formula of 40Na2O-12.5Gd2O3-5SiO2-(41.5)B2O3-1Dy2O3 was investigated Judd-Ofelt (J-O) and Fourier-transform infrared spectroscopy (FTIR). The J-O intensity characteristics are calculated from the integrated area under absorption and emission, as well as refractive index. Utilizing the J-O method, optical characteristics such as oscillator strengths, J-O parameter, radiative transition probability, the stimulated emission cross-section, and branching ratios are determined. FTIR method was utilized to determine the characteristic functional groups contained in the chemical structure of composites based on its matrix.
